Grid system

Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes predefined classes for easy layout options, as well as powerful mixins for generating more semantic layouts.

Make Sure to Always Plan a Responsive Layout

It takes a minute or two extra – not more than that. Just make sure you always make your UI responsive. It is as simple as considering how .col-xx-x classes break down on smaller screens.

Introduction

Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Bootstrap grid system works:

Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.
Use rows to create horizontal groups of columns.
Content should be placed within columns, and only columns may be immediate children of rows.
Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
The negative margin is why the examples below are outdented. It's so that content within grid columns is lined up with non-grid content.
Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.
If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, e.g. applying any .col-md-* class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg-* class is not present.

Look to the examples for applying these principles to your code.

Media queries

We use the following media queries in our Less files to create the key breakpoints in our grid system.

/* Extra small devices (phones, less than 768px) */
							/* No media query since this is the default in Bootstrap */
							/* Small devices (tablets, 768px and up) */
							@media (
							min-width:
							@screen-sm-min)
							{ ... }
							/* Medium devices (desktops, 992px and up) */
							@media
							(min-width: @
							screen-md-min)
							{ ...
							}
							/* Large devices (large desktops, 1200px and up) */
							@media (min-width: @screen-lg-min)
							{ ... }

We occasionally expand on these media queries to include a max-width to limit CSS to a narrower set of devices.


							@media (max-width
							: @screen-xs-max)
							{ ... }
							@media (min-width: @screen-sm-min) and (max-width: @screen-sm-max) { ... }
							@media (min-width: @screen-md-min) and (max-width: @screen-md-max) { ... }
							@media (min-width: @screen-lg-min) { ... }

A Word About Pixel Values And Viewport Sizes

The most important information is that these viewport pixel values don't necessarily correlate with the native resolution of any mobile device. By setting <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">, the HTML header forces Webkit/Chromium into a rendering mode which simulates (on phones) a 240x320px resolution. Scaling and antialiasing work correctly, so a much higher screen resolution means crystal clear rendering regardless. This allows Bootstrap's CSS to test against a pixel width of the viewport. If we don't define the scale of the viewport, a phone is indistinguishable from a tablet, laptop or desktop screen. In summary, rejoice, but don't pay too much attention to the pixel values used by Bootstrap.

Grid options

See how aspects of the Bootstrap grid system work across multiple devices with a handy table.

	Extra small devices Phones (<768px)	Small devices Tablets (≥768px)	Medium devices Desktops (≥992px)	Large devices Desktops (≥1200px)
Grid behavior	Horizontal at all times	Collapsed to start, horizontal above breakpoints
Container width	None (auto)	750px	970px	1170px
Class prefix	`.col-xs-`	`.col-sm-`	`.col-md-`	`.col-lg-`
# of columns	12
Column width	Auto	~62px	~81px	~97px
Gutter width	30px (15px on each side of a column)
Nestable	Yes
Offsets	Yes
Column ordering	Yes

Example: Stacked-to-horizontal

Using a single set of .col-md-* grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices. Place grid columns in any .row.

.col-md-1

.col-md-8

.col-md-4

.col-md-6

<div class="row">
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			  <div class="col-md-1">.col-md-1</div>
			</div>
			<div class="row">
			  <div class="col-md-8">.col-md-8</div>
			  <div class="col-md-4">.col-md-4</div>
			</div>
			<div class="row">
			  <div class="col-md-4">.col-md-4</div>
			  <div class="col-md-4">.col-md-4</div>
			  <div class="col-md-4">.col-md-4</div>
			</div>
			<div class="row">
			  <div class="col-md-6">.col-md-6</div>
			  <div class="col-md-6">.col-md-6</div>
			</div>

Example: Fluid container

Turn any fixed-width grid layout into a full-width layout by changing your outermost .container to .container-fluid.

<div class="container-fluid">
			  <div class="row">
			    ...
			  </div>
			</div>

Example: Mobile and desktop

Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding .col-xs-* .col-md-* to your columns. See the example below for a better idea of how it all works.

.col-xs-12 .col-md-8

.col-xs-6 .col-md-4

.col-xs-6

<!-- Stack the columns on mobile by making one full-width and the other half-width -->
			<div class="row">
			  <div class="col-xs-12 col-md-8">.col-xs-12 .col-md-8</div>
			  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
			</div>

			<!-- Columns start at 50% wide on mobile and bump up to 33.3% wide on desktop -->
			<div class="row">
			  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
			  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
			  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
			</div>

			<!-- Columns are always 50% wide, on mobile and desktop -->
			<div class="row">
			  <div class="col-xs-6">.col-xs-6</div>
			  <div class="col-xs-6">.col-xs-6</div>
			</div>

Example: Mobile, tablet, desktop

Build on the previous example by creating even more dynamic and powerful layouts with tablet .col-sm-* classes.

.col-xs-12 .col-sm-6 .col-md-8

.col-xs-6 .col-md-4

.col-xs-6 .col-sm-4

<div class="row">
			  <div class="col-xs-12 col-sm-6 col-md-8">.col-xs-12 .col-sm-6 .col-md-8</div>
			  <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
			</div>
			<div class="row">
			  <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
			  <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
			  <!-- Optional: clear the XS cols if their content doesn't match in height -->
			  <div class="clearfix visible-xs-block"></div>
			  <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
			</div>

Example: Column wrapping

If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.

.col-xs-9

.col-xs-4
Since 9 + 4 = 13 > 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.

.col-xs-6
Subsequent columns continue along the new line.

<div class="row">
			  <div class="col-xs-9">.col-xs-9</div>
			  <div class="col-xs-4">.col-xs-4<br>Since 9 + 4 = 13 &gt; 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.</div>
			  <div class="col-xs-6">.col-xs-6<br>Subsequent columns continue along the new line.</div>
			</div>

Responsive column resets

With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and our responsive utility classes.

.col-xs-6 .col-sm-3
Resize your viewport or check it out on your phone for an example.

.col-xs-6 .col-sm-3

<div class="row">
			  <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
			  <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>

			  <!-- Add the extra clearfix for only the required viewport -->
			  <div class="clearfix visible-xs-block"></div>

			  <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
			  <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
			</div>

In addition to column clearing at responsive breakpoints, you may need to reset offsets, pushes, or pulls. See this in action in the grid example.

<div class="row">
			  <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
			  <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
			</div>

			<div class="row">
			  <div class="col-sm-6 col-md-5 col-lg-6">.col-sm-6 .col-md-5 .col-lg-6</div>
			  <div class="col-sm-6 col-md-5 col-md-offset-2 col-lg-6 col-lg-offset-0">.col-sm-6 .col-md-5 .col-md-offset-2 .col-lg-6 .col-lg-offset-0</div>
			</div>

Offsetting columns

Move columns to the right using .col-md-offset-* classes. These classes increase the left margin of a column by * columns. For example, .col-md-offset-4 moves .col-md-4 over four columns.

.col-md-4

.col-md-4 .col-md-offset-4

.col-md-3 .col-md-offset-3

.col-md-6 .col-md-offset-3

<div class="row">
			  <div class="col-md-4">.col-md-4</div>
			  <div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
			</div>
			<div class="row">
			  <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
			  <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
			</div>
			<div class="row">
			  <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
			</div>

You can also override offsets from lower grid tiers with .col-*-offset-0 classes.

<div class="row">
			  <div class="col-xs-6 col-sm-4">
			  </div>
			  <div class="col-xs-6 col-sm-4">
			  </div>
			  <div class="col-xs-6 col-xs-offset-3 col-sm-4 col-sm-offset-0">
			  </div>
			</div>

Nesting columns

To nest your content with the default grid, add a new .row and set of .col-sm-* columns within an existing .col-sm-* column. Nested rows should include a set of columns that add up to 12 or fewer (it is not required that you use all 12 available columns).

Level 1: .col-sm-9

Level 2: .col-xs-8 .col-sm-6

Level 2: .col-xs-4 .col-sm-6

<div class="row">
			  <div class="col-sm-9">
			    Level 1: .col-sm-9
			    <div class="row">
			      <div class="col-xs-8 col-sm-6">
			        Level 2: .col-xs-8 .col-sm-6
			      </div>
			      <div class="col-xs-4 col-sm-6">
			        Level 2: .col-xs-4 .col-sm-6
			      </div>
			    </div>
			  </div>
			</div>

Column ordering

Easily change the order of our built-in grid columns with .col-md-push-* and .col-md-pull-* modifier classes.

.col-md-9 .col-md-push-3

.col-md-3 .col-md-pull-9

<div class="row">
			  <div class="col-md-9 col-md-push-3">.col-md-9 .col-md-push-3</div>
			  <div class="col-md-3 col-md-pull-9">.col-md-3 .col-md-pull-9</div>
			</div>

Less mixins and variables

In addition to prebuilt grid classes for fast layouts, Bootstrap includes Less variables and mixins for quickly generating your own simple, semantic layouts.

Variables

Variables determine the number of columns, the gutter width, and the media query point at which to begin floating columns. We use these to generate the predefined grid classes documented above, as well as for the custom mixins listed below.

@grid-columns:              12;
			@grid-gutter-width:         30px;
			@grid-float-breakpoint:     768px;

Mixins

Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.

// Creates a wrapper for a series of columns
			.make-row(@gutter: @grid-gutter-width) {
			  // Then clear the floated columns
			  .clearfix();

			  @media (min-width: @screen-sm-min) {
			    margin-left:  (@gutter / -2);
			    margin-right: (@gutter / -2);
			  }

			  // Negative margin nested rows out to align the content of columns
			  .row {
			    margin-left:  (@gutter / -2);
			    margin-right: (@gutter / -2);
			  }
			}

			// Generate the extra small columns
			.make-xs-column(@columns; @gutter: @grid-gutter-width) {
			  position: relative;
			  // Prevent columns from collapsing when empty
			  min-height: 1px;
			  // Inner gutter via padding
			  padding-left:  (@gutter / 2);
			  padding-right: (@gutter / 2);

			  // Calculate width based on number of columns available
			  @media (min-width: @grid-float-breakpoint) {
			    float: left;
			    width: percentage((@columns / @grid-columns));
			  }
			}

			// Generate the small columns
			.make-sm-column(@columns; @gutter: @grid-gutter-width) {
			  position: relative;
			  // Prevent columns from collapsing when empty
			  min-height: 1px;
			  // Inner gutter via padding
			  padding-left:  (@gutter / 2);
			  padding-right: (@gutter / 2);

			  // Calculate width based on number of columns available
			  @media (min-width: @screen-sm-min) {
			    float: left;
			    width: percentage((@columns / @grid-columns));
			  }
			}

			// Generate the small column offsets
			.make-sm-column-offset(@columns) {
			  @media (min-width: @screen-sm-min) {
			    margin-left: percentage((@columns / @grid-columns));
			  }
			}
			.make-sm-column-push(@columns) {
			  @media (min-width: @screen-sm-min) {
			    left: percentage((@columns / @grid-columns));
			  }
			}
			.make-sm-column-pull(@columns) {
			  @media (min-width: @screen-sm-min) {
			    right: percentage((@columns / @grid-columns));
			  }
			}

			// Generate the medium columns
			.make-md-column(@columns; @gutter: @grid-gutter-width) {
			  position: relative;
			  // Prevent columns from collapsing when empty
			  min-height: 1px;
			  // Inner gutter via padding
			  padding-left:  (@gutter / 2);
			  padding-right: (@gutter / 2);

			  // Calculate width based on number of columns available
			  @media (min-width: @screen-md-min) {
			    float: left;
			    width: percentage((@columns / @grid-columns));
			  }
			}

			// Generate the medium column offsets
			.make-md-column-offset(@columns) {
			  @media (min-width: @screen-md-min) {
			    margin-left: percentage((@columns / @grid-columns));
			  }
			}
			.make-md-column-push(@columns) {
			  @media (min-width: @screen-md-min) {
			    left: percentage((@columns / @grid-columns));
			  }
			}
			.make-md-column-pull(@columns) {
			  @media (min-width: @screen-md-min) {
			    right: percentage((@columns / @grid-columns));
			  }
			}

			// Generate the large columns
			.make-lg-column(@columns; @gutter: @grid-gutter-width) {
			  position: relative;
			  // Prevent columns from collapsing when empty
			  min-height: 1px;
			  // Inner gutter via padding
			  padding-left:  (@gutter / 2);
			  padding-right: (@gutter / 2);

			  // Calculate width based on number of columns available
			  @media (min-width: @screen-lg-min) {
			    float: left;
			    width: percentage((@columns / @grid-columns));
			  }
			}

			// Generate the large column offsets
			.make-lg-column-offset(@columns) {
			  @media (min-width: @screen-lg-min) {
			    margin-left: percentage((@columns / @grid-columns));
			  }
			}
			.make-lg-column-push(@columns) {
			  @media (min-width: @screen-lg-min) {
			    left: percentage((@columns / @grid-columns));
			  }
			}
			.make-lg-column-pull(@columns) {
			  @media (min-width: @screen-lg-min) {
			    right: percentage((@columns / @grid-columns));
			  }
			}

Example usage

You can modify the variables to your own custom values, or just use the mixins with their default values. Here's an example of using the default settings to create a two-column layout with a gap between.

.wrapper {
						.make-row();
						}
						.content-main {
			  			.make-lg-column(8);
						}
						.content-secondary {
			  			.make-lg-column(3);
			  			.make-lg-column-offset(1);
						}

<div class="wrapper">
			  			<div class="content-main">...</div>
			  			<div class="content-secondary">...</div>
						</div>

Headings

All HTML headings, <h1> through <h6>, are available. .h1 through .h6 classes are also available, for when you want to match the font styling of a heading but still want your text to be displayed inline.

h1. Bootstrap heading	Semibold 36px
h2. Bootstrap heading	Semibold 30px
h3. Bootstrap heading	Semibold 24px
h4. Bootstrap heading	Semibold 18px
h5. Bootstrap heading	Semibold 14px
h6. Bootstrap heading	Semibold 12px

<h1>h1. Bootstrap heading</h1>
						<h2>h2. Bootstrap heading</h2>
						<h3>h3. Bootstrap heading</h3>
						<h4>h4. Bootstrap heading</h4>
						<h5>h5. Bootstrap heading</h5>
						<h6>h6. Bootstrap heading</h6>

Create lighter, secondary text in any heading with a generic <small> tag or the .small class.

h1. Bootstrap heading Secondary text

h2. Bootstrap heading Secondary text

h3. Bootstrap heading Secondary text

h4. Bootstrap heading Secondary text

h5. Bootstrap heading Secondary text

h6. Bootstrap heading Secondary text

<h1>h1. Bootstrap heading <small>Secondary text</small></h1>
							<h2>h2. Bootstrap heading <small>Secondary text</small></h2>
							<h3>h3. Bootstrap heading <small>Secondary text</small></h3>
							<h4>h4. Bootstrap heading <small>Secondary text</small></h4>
							<h5>h5. Bootstrap heading <small>Secondary text</small></h5>
							<h6>h6. Bootstrap heading <small>Secondary text</small></h6>

Body copy

Bootstrap's global default font-size is 14px, with a line-height of 1.428. This is applied to the <body> and all paragraphs. In addition, <p> (paragraphs) receive a bottom margin of half their computed line-height (10px by default).

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Nullam id dolor id nibh ultricies vehicula.

Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec ullamcorper nulla non metus auctor fringilla. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Donec ullamcorper nulla non metus auctor fringilla.

Maecenas sed diam eget risus varius blandit sit amet non magna. Donec id elit non mi porta gravida at eget metus. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit.

<p>...</p>

Lead body copy

Make a paragraph stand out by adding .lead.

Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.

<p class="lead">...</p>

Built with Less

The typographic scale is based on two Less variables in variables.less: @font-size-base and @line-height-base. The first is the base font-size used throughout and the second is the base line-height. We use those variables and some simple math to create the margins, paddings, and line-heights of all our type and more. Customize them and Bootstrap adapts.

Inline text elements

Marked text

For highlighting a run of text due to its relevance in another context, use the <mark> tag.

You can use the mark tag to highlight text.

You can use the mark tag to <mark>highlight</mark> text.

Deleted text

For indicating blocks of text that have been deleted use the <del> tag.

~~This line of text is meant to be treated as deleted text.~~

<del>This line of text is meant to be treated as deleted text.</del>

Strikethrough text

For indicating blocks of text that are no longer relevant use the <s> tag.

~~This line of text is meant to be treated as no longer accurate.~~

<s>This line of text is meant to be treated as no longer accurate.</s>

Inserted text

For indicating additions to the document use the <ins> tag.

This line of text is meant to be treated as an addition to the document.

<ins>This line of text is meant to be treated as an addition to the document.</ins>

Underlined text

To underline text use the <u> tag.

This line of text will render as underlined

<u>This line of text will render as underlined</u>

Make use of HTML's default emphasis tags with lightweight styles.

Small text

For de-emphasizing inline or blocks of text, use the <small> tag to set text at 85% the size of the parent. Heading elements receive their own font-size for nested <small> elements.

You may alternatively use an inline element with .small in place of any <small>.

This line of text is meant to be treated as fine print.

<small>This line of text is meant to be treated as fine print.</small>

Bold

For emphasizing a snippet of text with a heavier font-weight.

The following snippet of text is rendered as bold text.

<strong>rendered as bold text</strong>

Italics

For emphasizing a snippet of text with italics.

The following snippet of text is rendered as italicized text.

<em>rendered as italicized text</em>

Alternate elements

Feel free to use <b> and <i> in HTML5. <b> is meant to highlight words or phrases without conveying additional importance while <i> is mostly for voice, technical terms, etc.

Alignment classes

Easily realign text to components with text alignment classes.

Left aligned text.

Center aligned text.

Right aligned text.

Justified text.

No wrap text.

<p class="text-left">Left aligned text.</p>
			<p class="text-center">Center aligned text.</p>
			<p class="text-right">Right aligned text.</p>
			<p class="text-justify">Justified text.</p>
			<p class="text-nowrap">No wrap text.</p>

Transformation classes

Transform text in components with text capitalization classes.

Lowercased text.

Uppercased text.

Capitalized text.

<p class="text-lowercase">Lowercased text.</p>
			<p class="text-uppercase">Uppercased text.</p>
			<p class="text-capitalize">Capitalized text.</p>

Abbreviations

Stylized implementation of HTML's <abbr> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations with a title attribute have a light dotted bottom border and a help cursor on hover, providing additional context on hover and to users of assistive technologies.

Basic abbreviation

An abbreviation of the word attribute is attr.

<abbr title="attribute">attr</abbr>

Initialism

Add .initialism to an abbreviation for a slightly smaller font-size.

HTML is the best thing since sliced bread.

<abbr title="HyperText Markup Language" class="initialism">HTML</abbr>

Addresses

Present contact information for the nearest ancestor or the entire body of work. Preserve formatting by ending all lines with <br>.

A simple shell for an h1 to appropriately space out and segment sections of content on a page. It can utilize the h1's default small element, as well as most other components (with additional styles).

<div class="page-header">
			  <h1>Example page header <small>Subtext for header</small></h1>
			</div>

Inline

Wrap inline snippets of code with <code>.

For example, <section> should be wrapped as inline.

For example, <code>
			        	&lt;section&gt;</code> should be wrapped as inline.

User input

Use the <kbd> to indicate input that is typically entered via keyboard.

To switch directories, type cd followed by the name of the directory.
To edit settings, press ctrl + ,

To switch directories, type <kbd>cd</kbd> followed by the name of the directory.
			        	<br>
						To edit settings, press <kbd><kbd>ctrl</kbd> + <kbd>,</kbd></kbd>

Basic block

Use <pre> for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.

<p>Sample text here...</p>

<pre>&lt;p&gt;Sample text here...&lt;/p&gt;</pre>

You may optionally add the .pre-scrollable class, which will set a max-height of 350px and provide a y-axis scrollbar.

Variables

For indicating variables use the <var> tag.

y = mx + b

<var>y</var> = <var>m</var><var>x</var> + <var>b</var>

Sample output

For indicating blocks sample output from a program use the <samp> tag.

This text is meant to be treated as sample output from a computer program.

<samp>This text is meant to be treated as sample output from a computer program.</samp>

Responsive images

Images in Bootstrap 3 can be made responsive-friendly via the addition of the .img-responsive class. This applies max-width: 100%;, height: auto; and display: block; to the image so that it scales nicely to the parent element.

To center images which use the .img-responsive class, use .center-block instead of .text-center. See the helper classes section for more details about .center-block usage.

SVG images and IE 8-10

In Internet Explorer 8-10, SVG images with .img-responsive are disproportionately sized. To fix this, add width: 100% \9; where necessary. Bootstrap doesn't apply this automatically as it causes complications to other image formats.

<img src="..." class="img-responsive" alt="Responsive image">

Image shapes

Add classes to an <img> element to easily style images in any project.

Cross-browser compatibility

Keep in mind that Internet Explorer 8 lacks support for rounded corners.

						class="img-thumbnail">

A lightweight, flexible component that can optionally extend the entire viewport to showcase key content on your site.

Hello, world!

This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.

Learn more

<div class="jumbotron">
			  <h1>Hello, world!</h1>
			  <p>...</p>
			  <p><a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a></p>
			</div>

To make the jumbotron full width, and without rounded corners, place it outside all .containers and instead add a .container within.

<div class="jumbotron">
			  <div class="container">
			    ...
			  </div>
			</div>

Contextual colors

Convey meaning through color with a handful of emphasis utility classes. These may also be applied to links and will darken on hover just like our default link styles.

Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.

Nullam id dolor id nibh ultricies vehicula ut id elit.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

Maecenas sed diam eget risus varius blandit sit amet non magna.

Etiam porta sem malesuada magna mollis euismod.

Donec ullamcorper nulla non metus auctor fringilla.

<p class="text-muted">...</p>
			<p class="text-primary">...</p>
			<p class="text-success">...</p>
			<p class="text-info">...</p>
			<p class="text-warning">...</p>
			<p class="text-danger">...</p>

Dealing with specificity

Sometimes emphasis classes cannot be applied due to the specificity of another selector. In most cases, a sufficient workaround is to wrap your text in a <span> with the class.

Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (the contextual colors are only used to reinforce meaning that is already present in the text/markup), or is included through alternative means, such as additional text hidden with the .sr-only class.

Contextual backgrounds

Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes.

Nullam id dolor id nibh ultricies vehicula ut id elit.

Duis mollis, est non commodo luctus, nisi erat porttitor ligula.

Maecenas sed diam eget risus varius blandit sit amet non magna.

Etiam porta sem malesuada magna mollis euismod.

Donec ullamcorper nulla non metus auctor fringilla.

<p class="bg-primary">...</p>
			<p class="bg-success">...</p>
			<p class="bg-info">...</p>
			<p class="bg-warning">...</p>
			<p class="bg-danger">...</p>

Dealing with specificity

Sometimes contextual background classes cannot be applied due to the specificity of another selector. In some cases, a sufficient workaround is to wrap your element's content in a <div> with the class.

Conveying meaning to assistive technologies

As with contextual colors, ensure that any meaning conveyed through color is also conveyed in a format that is not purely presentational.

Close icon

Use the generic close icon for dismissing content like modals and alerts.

<button type="button" class="close" aria-label="Close"><span aria-hidden="true">&times;</span></button>

Carets

Use carets to indicate dropdown functionality and direction. Note that the default caret will reverse automatically in dropup menus.

<span class="caret"></span>

Quick floats

Float an element to the left or right with a class. !important is included to avoid specificity issues. Classes can also be used as mixins.

<div class="pull-left">...</div>
			<div class="pull-right">...</div>

// Classes
			.pull-left {
			  float: left !important;
			}
			.pull-right {
			  float: right !important;
			}

			// Usage as mixins
			.element {
			  .pull-left();
			}
			.another-element {
			  .pull-right();
			}

Center content blocks

Set an element to display: block and center via margin. Available as a mixin and class.

<div class="center-block">...</div>

// Class
			.center-block {
			  display: block;
			  margin-left: auto;
			  margin-right: auto;
			}

			// Usage as a mixin
			.element {
			  .center-block();
			}

Clearfix

Easily clear floats by adding .clearfix to the parent element. Utilizes the micro clearfix as popularized by Nicolas Gallagher. Can also be used as a mixin.

<!-- Usage as a class -->
			<div class="clearfix">...</div>

// Mixin itself
			.clearfix() {
			  &:before,
			  &:after {
			    content: " ";
			    display: table;
			  }
			  &:after {
			    clear: both;
			  }
			}

			// Usage as a mixin
			.element {
			  .clearfix();
			}

Showing and hiding content

Force an element to be shown or hidden (including for screen readers) with the use of .show and .hidden classes. These classes use !important to avoid specificity conflicts, just like the quick floats. They are only available for block level toggling. They can also be used as mixins.

.hide is available, but it does not always affect screen readers and is deprecated as of v3.0.1. Use .hidden or .sr-only instead.

Furthermore, .invisible can be used to toggle only the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document.

<div class="show">...</div>
			<div class="hidden">...</div>

// Classes
			.show {
			  display: block !important;
			}
			.hidden {
			  display: none !important;
			}
			.invisible {
			  visibility: hidden;
			}

			// Usage as mixins
			.element {
			  .show();
			}
			.another-element {
			  .hidden();
			}

Screen reader and keyboard navigation content

Hide an element to all devices except screen readers with .sr-only. Combine .sr-only with .sr-only-focusable to show the element again when it's focused (e.g. by a keyboard-only user). Necessary for following accessibility best practices. Can also be used as mixins.

<a class="sr-only sr-only-focusable" href="#content">Skip to main content</a>

// Usage as a mixin
			.skip-navigation {
			  .sr-only();
			  .sr-only-focusable();
			}

Image replacement

Utilize the .text-hide class or mixin to help replace an element's text content with a background image.

<h1 class="text-hide">Custom heading</h1>

// Usage as a mixin
			.heading {
			  .text-hide();
			}

For faster mobile-friendly development, use these utility classes for showing and hiding content by device via media query. Also included are utility classes for toggling content when printed.

Try to use these on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation.

Available classes

Use a single or combination of the available classes for toggling content across viewport breakpoints.

	Extra small devices Phones (<768px)	Small devices Tablets (≥768px)	Medium devices Desktops (≥992px)	Large devices Desktops (≥1200px)
`.visible-xs-*`	Visible	Hidden	Hidden	Hidden
`.visible-sm-*`	Hidden	Visible	Hidden	Hidden
`.visible-md-*`	Hidden	Hidden	Visible	Hidden
`.visible-lg-*`	Hidden	Hidden	Hidden	Visible
`.hidden-xs`	Hidden	Visible	Visible	Visible
`.hidden-sm`	Visible	Hidden	Visible	Visible
`.hidden-md`	Visible	Visible	Hidden	Visible
`.hidden-lg`	Visible	Visible	Visible	Hidden

As of v3.2.0, the .visible-*-* classes for each breakpoint come in three variations, one for each CSS display property value listed below.

Group of classes	CSS `display`
`.visible-*-block`	`display: block;`
`.visible-*-inline`	`display: inline;`
`.visible-*-inline-block`	`display: inline-block;`

So, for extra small (xs) screens for example, the available .visible-*-* classes are: .visible-xs-block, .visible-xs-inline, and .visible-xs-inline-block.

The classes .visible-xs, .visible-sm, .visible-md, and .visible-lg also exist, but are deprecated as of v3.2.0. They are approximately equivalent to .visible-*-block, except with additional special cases for toggling <table>-related elements.

Print classes

Similar to the regular responsive classes, use these for toggling content for print.

Classes	Browser	Print
`.visible-print-block` `.visible-print-inline` `.visible-print-inline-block`	Hidden	Visible
`.hidden-print`	Visible	Hidden

The class .visible-print also exists but is deprecated as of v3.2.0. It is approximately equivalent to .visible-print-block, except with additional special cases for <table>-related elements.

Test cases

Resize your browser or load on different devices to test the responsive utility classes.

Example

Example heading New

<h3>Example heading <span class="label label-default">New</span></h3>

Available variations

Add any of the below mentioned modifier classes to change the appearance of a label.

Default Primary Success Info Warning Danger

<span class="label label-default">Default</span>
						<span class="label label-primary">Primary</span>
						<span class="label label-success">Success</span>
						<span class="label label-info">Info</span>
						<span class="label label-warning">Warning</span>
						<span class="label label-danger">Danger</span>

Have tons of labels?

Rendering problems can arise when you have dozens of inline labels within a narrow container, each containing its own inline-block element (like an icon). The way around this is setting display: inline-block;. For context and an example, see #13219.

DL Labels

Labels can be constructed from <DL> elements. These labels consist of at least two strings, each wrapped in its own element: attrib <dt> and value <dd>. A single dl.label can contain multiple <dt> and <dd> elements in every possible combination.

Easily highlight new or unread items by adding a <span class="badge"> to links, Bootstrap navs, and more.

Inbox 42

<a href="#">Inbox <span class="badge">42</span></a>
			<button class="btn btn-primary" type="button">
			  Messages <span class="badge">4</span>
			</button>

Self collapsing

When there are no new or unread items, badges will simply collapse (via CSS's :empty selector) provided no content exists within.

Cross-browser compatibility

Badges won't self collapse in Internet Explorer 8 because it lacks support for the :empty selector.

Adapts to active nav states

Built-in styles are included for placing badges in active states in pill navigations.

<ul class="nav nav-pills" role="tablist">
			  <li role="presentation" class="active"><a href="#">Home <span class="badge">42</span></a></li>
			  <li role="presentation"><a href="#">Profile</a></li>
			  <li role="presentation"><a href="#">Messages <span class="badge">3</span></a></li>
			</ul>

Extend Bootstrap's grid system with the thumbnail component to easily display grids of images, videos, text, and more.

If you're looking for Pinterest-like presentation of thumbnails of varying heights and/or widths, you'll need to use a third-party plugin such as Masonry, Isotope, or Salvattore.

Default example

By default, Bootstrap's thumbnails are designed to showcase linked images with minimal required markup.

<div class="row">
			  <div class="col-xs-6 col-md-3">
			    <a href="#" class="thumbnail">
			      <img src="..." alt="...">
			    </a>
			  </div>
			  ...
			</div>

Custom content

With a bit of extra markup, it's possible to add any kind of HTML content like headings, paragraphs, or buttons into thumbnails.

Thumbnail label

Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.

Button Button

Thumbnail label

Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.

			  <div class="col-sm-6 col-md-4">
			    <div class="thumbnail">
			      <img src="..." alt="...">
			      <div class="caption">
			        <h3>Thumbnail label</h3>
			        <p>...</p>
			        <p><a href="#" class="btn btn-primary" role="button">Button</a> <a href="#" class="btn btn-default" role="button">Button</a></p>
			      </div>
			    </div>
			  </div>
			</div>

Callouts (as used in the Bootstrap documentation) are used instead of the standard alerts. Each callout must contain a headline <h4> and at least one content element, default is <p>.

Info Callout

Use this to explain to the user what is happening, or how to use a complex interface.

Warning Callout

Warn the user of something that is about to happen.

Danger Callout

Warn the user of something that has happened.

Provide contextual feedback messages for typical user actions with the handful of available and flexible alert messages.

Examples

Wrap any text and an optional dismiss button in .alert and one of the four contextual classes (e.g., .alert-success) for basic alert messages.

No default class

Alerts don't have default classes, only base and modifier classes. A default gray alert doesn't make too much sense, so you're required to specify a type via contextual class. Choose from success, info, warning, or danger.

Well done! You successfully read this important alert message.

Heads up! This alert needs your attention, but it's not super important.

Warning! Better check yourself, you're not looking too good.

Oh snap! Change a few things up and try submitting again.

<div class="alert alert-success" role="alert">...</div>
			<div class="alert alert-info" role="alert">...</div>
			<div class="alert alert-warning" role="alert">...</div>
			<div class="alert alert-danger" role="alert">...</div>

Dismissible alerts

Build on any alert by adding an optional .alert-dismissible and close button.

Requires JavaScript alert plugin

For fully functioning, dismissible alerts, you must use the alerts JavaScript plugin.

Warning! Better check yourself, you're not looking too good.

<div class="alert alert-warning alert-dismissible" role="alert">
			  <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
			  <strong>Warning!</strong> Better check yourself, you're not looking too good.
			</div>

Ensure proper behavior across all devices

Be sure to use the <button> element with the data-dismiss="alert" data attribute.

Links in alerts

Use the .alert-link utility class to quickly provide matching colored links within any alert.

Well done! You successfully read this important alert message.

Heads up! This alert needs your attention, but it's not super important.

Warning! Better check yourself, you're not looking too good.

Oh snap! Change a few things up and try submitting again.

<div class="alert alert-success" role="alert">
			  <a href="#" class="alert-link">...</a>
			</div>
			<div class="alert alert-info" role="alert">
			  <a href="#" class="alert-link">...</a>
			</div>
			<div class="alert alert-warning" role="alert">
			  <a href="#" class="alert-link">...</a>
			</div>
			<div class="alert alert-danger" role="alert">
			  <a href="#" class="alert-link">...</a>
			</div>

Provide up-to-date feedback on the progress of a workflow or action with simple yet flexible progress bars.

Cross-browser compatibility

Progress bars use CSS3 transitions and animations to achieve some of their effects. These features are not supported in Internet Explorer 9 and below or older versions of Firefox. Opera 12 does not support animations.

Content Security Policy (CSP) compatibility

If your website has a Content Security Policy (CSP) which doesn't allow style-src 'unsafe-inline', then you won't be able to use inline style attributes to set progress bar widths as shown in our examples below. Alternative methods for setting the widths that are compatible with strict CSPs include using a little custom JavaScript (that sets element.style.width) or using custom CSS classes.

Basic example

Default progress bar.

<div class="progress">
			  <div class="progress-bar" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">
			    <span class="sr-only">60% Complete</span>
			  </div>
			</div>

With label

Remove the <span> with .sr-only class from within the progress bar to show a visible percentage.

60%

<div class="progress">
			  <div class="progress-bar" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%;">
			    60%
			  </div>
			</div>

To ensure that the label text remains legible even for low percentages, consider adding a min-width to the progress bar.

<div class="progress">
			  <div class="progress-bar" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100" style="min-width: 2em;">
			    0%
			  </div>
			</div>
			<div class="progress">
			  <div class="progress-bar" role="progressbar" aria-valuenow="2" aria-valuemin="0" aria-valuemax="100" style="min-width: 2em; width: 2%;">
			    2%
			  </div>
			</div>

Contextual alternatives

Progress bars use some of the same button and alert classes for consistent styles.

<div class="progress">
			  <div class="progress-bar progress-bar-success" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 40%">
			    <span class="sr-only">40% Complete (success)</span>
			  </div>
			</div>
			<div class="progress">
			  <div class="progress-bar progress-bar-info" role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" style="width: 20%">
			    <span class="sr-only">20% Complete</span>
			  </div>
			</div>
			<div class="progress">
			  <div class="progress-bar progress-bar-warning" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%">
			    <span class="sr-only">60% Complete (warning)</span>
			  </div>
			</div>
			<div class="progress">
			  <div class="progress-bar progress-bar-danger" role="progressbar" aria-valuenow="80" aria-valuemin="0" aria-valuemax="100" style="width: 80%">
			    <span class="sr-only">80% Complete (danger)</span>
			  </div>
			</div>

Striped

Uses a gradient to create a striped effect. Not available in IE9 and below.

<div class="progress">
			  <div class="progress-bar progress-bar-success progress-bar-striped" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 40%">
			    <span class="sr-only">40% Complete (success)</span>
			  </div>
			</div>
			<div class="progress">
			  <div class="progress-bar progress-bar-info progress-bar-striped" role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" style="width: 20%">
			    <span class="sr-only">20% Complete</span>
			  </div>
			</div>
			<div class="progress">
			  <div class="progress-bar progress-bar-warning progress-bar-striped" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 60%">
			    <span class="sr-only">60% Complete (warning)</span>
			  </div>
			</div>
			<div class="progress">
			  <div class="progress-bar progress-bar-danger progress-bar-striped" role="progressbar" aria-valuenow="80" aria-valuemin="0" aria-valuemax="100" style="width: 80%">
			    <span class="sr-only">80% Complete (danger)</span>
			  </div>
			</div>

Animated

Add .active to .progress-bar-striped to animate the stripes right to left. Not available in IE9 and below.

<div class="progress">
			  <div class="progress-bar progress-bar-striped active" role="progressbar" aria-valuenow="45" aria-valuemin="0" aria-valuemax="100" style="width: 45%">
			    <span class="sr-only">45% Complete</span>
			  </div>
			</div>

Stacked

Place multiple bars into the same .progress to stack them.

<div class="progress">
			  <div class="progress-bar progress-bar-success" style="width: 35%">
			    <span class="sr-only">35% Complete (success)</span>
			  </div>
			  <div class="progress-bar progress-bar-warning progress-bar-striped" style="width: 20%">
			    <span class="sr-only">20% Complete (warning)</span>
			  </div>
			  <div class="progress-bar progress-bar-danger" style="width: 10%">
			    <span class="sr-only">10% Complete (danger)</span>
			  </div>
			</div>

Abstract object styles for building various types of components (like blog comments, Tweets, etc) that feature a left- or right-aligned image alongside textual content.

Default media

The default media displays a media object (images, video, audio) to the left or right of a content block.

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

Media heading

Nested media heading

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.

<div class="media">
			  <div class="media-left">
			    <a href="#">
			      <img class="media-object" src="..." alt="...">
			    </a>
			  </div>
			  <div class="media-body">
			    <h4 class="media-heading">Media heading</h4>
			    ...
			  </div>
			</div>

The classes .pull-left and .pull-right also exist and were previously used as part of the media component, but are deprecated for that use as of v3.3.0. They are approximately equivalent to .media-left and .media-right, except that .media-right should be placed after the .media-body in the html.

Media alignment

The images or other media can be aligned top, middle, or bottom. The default is top aligned.

Top aligned media

Donec sed odio dui. Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

Middle aligned media

Donec sed odio dui. Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

Bottom aligned media

Donec sed odio dui. Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

<div class="media">

Media list

With a bit of extra markup, you can use media inside list (useful for comment threads or articles lists).

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.

Nested media heading
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis.

Allow browsers to determine video or slideshow dimensions based on the width of their containing block by creating an intrinsic ratio that will properly scale on any device.

Rules are directly applied to <iframe>, <embed>, <video>, and <object> elements; optionally use an explicit descendant class .embed-responsive-item when you want to match the styling for other attributes.

Pro-Tip! You don't need to include frameborder="0" in your <iframe>s as we override that for you.

<!-- 16:9 aspect ratio -->
			<div class="embed-responsive embed-responsive-16by9">
			  <iframe class="embed-responsive-item" src="..."></iframe>
			</div>

			<!-- 4:3 aspect ratio -->
			<div class="embed-responsive embed-responsive-4by3">
			  <iframe class="embed-responsive-item" src="..."></iframe>
			</div>

Default well

Use the well as a simple effect on an element to give it an inset effect.

Look, I'm in a well!

<div class="well">...</div>

Optional classes

Control padding and rounded corners with two optional modifier classes.

Look, I'm in a large well!

<div class="well well-lg">...</div>

Look, I'm in a small well!

<div class="well well-sm">...</div>

While not always necessary, sometimes you need to put your DOM in a box. For those situations, try the panel component.

Basic example

By default, all the .panel does is apply some basic border and padding to contain some content.

Basic panel example

<div class="panel panel-default">
			  <div class="panel-body">
			    Basic panel example
			  </div>
			</div>

Panel with heading

Easily add a heading container to your panel with .panel-heading. You may also include any <h1>-<h6> with a .panel-title class to add a pre-styled heading. However, the font sizes of <h1>-<h6> are overridden by .panel-heading.

For proper link coloring, be sure to place links in headings within .panel-title.

			<div class="panel panel-default">
			  <div class="panel-heading">
			    <h3 class="panel-title">Panel title</h3>
			  </div>
			  <div class="panel-body">
			    Panel content
			  </div>
			</div>

Panel with footer

Wrap buttons or secondary text in .panel-footer. Note that panel footers do not inherit colors and borders when using contextual variations as they are not meant to be in the foreground.

Panel content

Panel footer

<div class="panel panel-default">
			  <div class="panel-body">
			    Panel content
			  </div>
			  <div class="panel-footer">Panel footer</div>
			</div>

Contextual alternatives

Like other components, easily make a panel more meaningful to a particular context by adding any of the contextual state classes.

			<div class="panel panel-info">...</div>
			<div class="panel panel-warning">...</div>
			<div class="panel panel-danger">...</div>

With tables

Add any non-bordered .table within a panel for a seamless design. If there is a .panel-body, we add an extra border to the top of the table for separation.

Panel heading

Some default panel content here. Nulla vitae elit libero, a pharetra augue. Aenean lacinia bibendum nulla sed consectetur. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum. Nullam id dolor id nibh ultricies vehicula ut id elit.

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

<div class="panel panel-default">
			  <!-- Default panel contents -->
			  <div class="panel-heading">Panel heading</div>
			  <div class="panel-body">
			    <p>...</p>
			  </div>

			  <!-- Table -->
			  <table class="table">
			    ...
			  </table>
			</div>

If there is no panel body, the component moves from panel header to table without interruption.

Panel heading

#	First Name	Last Name	Username
1	Mark	Otto	@mdo
2	Jacob	Thornton	@fat
3	Larry	the Bird	@twitter

<div class="panel panel-default">
			  <!-- Default panel contents -->
			  <div class="panel-heading">Panel heading</div>

			  <!-- Table -->
			  <table class="table">
			    ...
			  </table>
			</div>

With list groups

Easily include full-width list groups within any panel.

Panel heading

Cras justo odio
Dapibus ac facilisis in
Morbi leo risus
Porta ac consectetur ac
Vestibulum at eros

<div class="panel panel-default">
			  <!-- Default panel contents -->
			  <div class="panel-heading">Panel heading</div>
			  <div class="panel-body">
			    <p>...</p>
			  </div>

			  <!-- List group -->
			  <ul class="list-group">
			    <li class="list-group-item">Cras justo odio</li>
			    <li class="list-group-item">Dapibus ac facilisis in</li>
			    <li class="list-group-item">Morbi leo risus</li>
			    <li class="list-group-item">Porta ac consectetur ac</li>
			    <li class="list-group-item">Vestibulum at eros</li>
			  </ul>
			</div>
