Include it at the beginning of all your projects. <div class="highlight"><pre><code class="html"><!DOCTYPE html> <html lang="en"> ... </html> </code></pre></div> <h3 id="overview-mobile">Mobile first</h3> With Bootstrap 2, we added optional mobile friendly styles for key aspects of the framework. With Bootstrap 3, we've rewritten the project to be mobile friendly from the start. Instead of adding on optional mobile styles, they're baked right into the core. In fact, Bootstrap is mobile first. Mobile first styles can be found throughout the entire library instead of in separate files. To ensure proper rendering and touch zooming, add the viewport meta tag to your <code><head></code>. <div class="highlight"><pre><code class="html"><meta name="viewport" content="width=device-width, initial-scale=1"> </code></pre></div> You can disable zooming capabilities on mobile devices by adding <code>user-scalable=no</code> to the viewport meta tag. This disables zooming, meaning users are only able to scroll, and results in your site feeling a bit more like a native application. Overall, we don't recommend this on every site, so use caution! <div class="highlight"><pre><code class="html"><meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"> </code></pre></div> <h3 id="overview-type-links">Typography and links</h3> Bootstrap sets basic global display, typography, and link styles. Specifically, we: <ul> <li>Set <code>background-color: #fff;</code> on the <code>body</code></li> <li>Use the <code>@font-family-base</code>, <code>@font-size-base</code>, and <code>@line-height-base</code> attributes as our typographic base</li> <li>Set the global link color via <code>@link-color</code> and apply link underlines only on <code>:hover</code></li> </ul> These styles can be found within <code>scaffolding.less</code>. <h3 id="overview-normalize">Normalize.css</h3> For improved cross-browser rendering, we use <a href="http://necolas.github.io/normalize.css/" target="_blank">Normalize.css</a>, a project by <a href="http://twitter.com/necolas" target="_blank">Nicolas Gallagher</a> and <a href="http://twitter.com/jon_neal" target="_blank">Jonathan Neal</a>. <h3 id="overview-container">Containers</h3> Easily center a page's contents by wrapping its contents in a <code>.container</code>. Containers set <code>width</code> at various media query breakpoints to match our grid system. Note that, due to <code>padding</code> and fixed widths, containers are not nestable by default. <div class="highlight"><pre><code class="html"><div class="container"> ... </div> </code></pre></div> </div>  <div class="bs-docs-section"> <h1 id="grid" class="page-header">Grid system</h1> 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 <a href="#grid-example-basic">predefined classes</a> for easy layout options, as well as powerful <a href="#grid-less">mixins for generating more semantic layouts</a>. <h3 id="grid-intro">Introduction</h3> 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: <ul> <li>Rows must be placed within a <code>.container</code> (fixed-width) or <code>.container-fluid</code> (full-width) for proper alignment and padding.</li> <li>Use rows to create horizontal groups of columns.</li> <li>Content should be placed within columns, and only columns may be immediate children of rows.</li> <li>Predefined grid classes like <code>.row</code> and <code>.col-xs-4</code> are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.</li> <li>Columns create gutters (gaps between column content) via <code>padding</code>. That padding is offset in rows for the first and last column via negative margin on <code>.row</code>s.</li> <li>Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three <code>.col-xs-4</code>.</li> </ul> Look to the examples for applying these principles to your code. <h3 id="grid-media-queries">Media queries</h3> We use the following media queries in our Less files to create the key breakpoints in our grid system. <div class="highlight"><pre><code class="scss">/* 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) { ... } </code></pre></div> We occasionally expand on these media queries to include a <code>max-width</code> to limit CSS to a narrower set of devices. <div class="highlight"><pre><code class="scss">@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) { ... } </code></pre></div> <h3 id="grid-options">Grid options</h3> See how aspects of the Bootstrap grid system work across multiple devices with a handy table. <div class="table-responsive"> <table class="table table-bordered table-striped"> <thead> <tr> <th></th> <th> Extra small devices Phones (<768px) </th> <th> Small devices Tablets (≥768px) </th> <th> Medium devices Desktops (≥992px) </th> <th> Large devices Desktops (≥1200px) </th> </tr> </thead> <tbody> <tr> <th>Grid behavior</th> <td>Horizontal at all times</td> <td colspan="3">Collapsed to start, horizontal above breakpoints</td> </tr> <tr> <th>Container width</th> <td>None (auto)</td> <td>750px</td> <td>970px</td> <td>1170px</td> </tr> <tr> <th>Class prefix</th> <td><code>.col-xs-</code></td> <td><code>.col-sm-</code></td> <td><code>.col-md-</code></td> <td><code>.col-lg-</code></td> </tr> <tr> <th># of columns</th> <td colspan="4">12</td> </tr> <tr> <th>Column width</th> <td class="text-muted">Auto</td> <td>60px</td> <td>78px</td> <td>95px</td> </tr> <tr> <th>Gutter width</th> <td colspan="4">30px (15px on each side of a column)</td> </tr> <tr> <th>Nestable</th> <td colspan="4">Yes</td> </tr> <tr> <th>Offsets</th> <td colspan="4">Yes</td> </tr> <tr> <th>Column ordering</th> <td colspan="4">Yes</td> </tr> </tbody> </table> </div> 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, applying any <code>.col-md-</code> class to an element will not only affect its styling on medium devices but also on large devices if a <code>.col-lg-</code> class is not present. <h3 id="grid-example-basic">Example: Stacked-to-horizontal</h3> Using a single set of <code>.col-md-*</code> 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 <code>.row</code>. <div class="bs-docs-grid"> <div class="row show-grid"> <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 show-grid"> <div class="col-md-8">.col-md-8</div> <div class="col-md-4">.col-md-4</div> </div> <div class="row show-grid"> <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 show-grid"> <div class="col-md-6">.col-md-6</div> <div class="col-md-6">.col-md-6</div> </div> </div> <div class="highlight"><pre><code class="html"><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> </code></pre></div> <h3 id="grid-example-fluid">Example: Fluid container</h3> Turn any fixed-width grid layout into a full-width layout by changing your outermost <code>.container</code> to <code>.container-fluid</code>. <div class="highlight"><pre><code class="html"><div class="container-fluid"> <div class="row"> ... </div> </div> </code></pre></div> <h3 id="grid-example-mixed">Example: Mobile and desktop</h3> Don't want your columns to simply stack in smaller devices?
