<!-- Global Bootstrap settings
================================================== -->
<div class="bs-docs-section">
<h1 id="overview" class="page-header">Overview</h1>
<p class="lead">Get the lowdown on the key pieces of Bootstrap's infrastructure, including our approach to better, faster, stronger web development.</p>
<h3 id="overview-doctype">HTML5 doctype</h3>
<p>Bootstrap makes use of certain HTML elements and CSS properties that require the use of the HTML5 doctype. Include it at the beginning of all your projects.</p>
<div class="highlight"><pre><code class="html"><span class="cp"><!DOCTYPE html></span>
<span class="nt"><html</span> <span class="na">lang=</span><span class="s">"en"</span><span class="nt">></span>
...
<span class="nt"></html></span>
</code></pre></div>
<h3 id="overview-mobile">Mobile first</h3>
<p>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, <strong>Bootstrap is mobile first</strong>. Mobile first styles can be found throughout the entire library instead of in separate files.</p>
<p>To ensure proper rendering and touch zooming, <strong>add the viewport meta tag</strong> to your <code><head></code>.</p>
<div class="highlight"><pre><code class="html"><span class="nt"><meta</span> <span class="na">name=</span><span class="s">"viewport"</span> <span class="na">content=</span><span class="s">"width=device-width, initial-scale=1"</span><span class="nt">></span>
</code></pre></div>
<p>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!</p>
<div class="highlight"><pre><code class="html"><span class="nt"><meta</span> <span class="na">name=</span><span class="s">"viewport"</span> <span class="na">content=</span><span class="s">"width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"</span><span class="nt">></span>
</code></pre></div>
<h3 id="overview-type-links">Typography and links</h3>
<p>Bootstrap sets basic global display, typography, and link styles. Specifically, we:</p>
<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>
<p>These styles can be found within <code>scaffolding.less</code>.</p>
<h3 id="overview-normalize">Normalize.css</h3>
<p>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>.</p>
<h3 id="overview-container">Containers</h3>
<p>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.</p>
<p>Note that, due to <code>padding</code> and fixed widths, containers are not nestable by default.</p>
<div class="highlight"><pre><code class="html"><span class="nt"><div</span> <span class="na">class=</span><span class="s">"container"</span><span class="nt">></span>
...
<span class="nt"></div></span>
</code></pre></div>
</div>
<!-- Grid system
================================================== -->
<div class="bs-docs-section">
<h1 id="grid" class="page-header">Grid system</h1>
<p class="lead">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>.</p>
<h3 id="grid-intro">Introduction</h3>
<p>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:</p>
<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>
<p>Look to the examples for applying these principles to your code.</p>

<p>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.</p>
<h3 id="grid-example-basic">Example: Stacked-to-horizontal</h3>
<p>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>.</p>

<h3 id="grid-less">Less mixins and variables</h3>
<p>In addition to <a href="#grid-example-basic">prebuilt grid classes</a> for fast layouts, Bootstrap includes Less variables and mixins for quickly generating your own simple, semantic layouts.</p>
<h4>Variables</h4>
<p>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.</p>
<div class="highlight"><pre><code class="scss"><span class="k">@grid-columns</span><span class="nd">:</span> <span class="nt">12</span><span class="o">;</span>

<span class="o">@</span><span class="nt">grid-float-breakpoint</span><span class="nd">:</span> <span class="nt">768px</span><span class="o">;</span>
</code></pre></div>
<h4>Mixins</h4>
<p>Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.</p>

<p>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.</p>
<p>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.</p>
<p>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>

<div class="highlight"><pre><code class="html"><span class="nt"><p></span>...<span class="nt"></p></span>
</code></pre></div>
<!-- Body copy .lead -->
<h3>Lead body copy</h3>
<p>Make a paragraph stand out by adding <code>.lead</code>.</p>
<div class="bs-example">
<p class="lead">Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.</p>
</div>

<!-- Using Less -->
<h3>Built with Less</h3>
<p>The typographic scale is based on two Less variables in <strong>variables.less</strong>: <code>@font-size-base</code> and <code>@line-height-base</code>. 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.</p>
<!-- Emphasis -->
<h2 id="type-emphasis">Emphasis</h2>
<p>Make use of HTML's default emphasis tags with lightweight styles.</p>
<h3>Small text</h3>
<p>For de-emphasizing inline or blocks of text, use the <code><small></code> tag to set text at 85% the size of the parent. Heading elements receive their own <code>font-size</code> for nested <code><small></code> elements.</p>
<p>You may alternatively use an inline element with <code>.small</code> in place of any <code><small></code>.</p>
<div class="bs-example">
<p><small>This line of text is meant to be treated as fine print.</small></p>
</div>
<div class="highlight"><pre><code class="html"><span class="nt"><small></span>This line of text is meant to be treated as fine print.<span class="nt"></small></span>
</code></pre></div>
<h3>Bold</h3>
<p>For emphasizing a snippet of text with a heavier font-weight.</p>
<div class="bs-example">
<p>The following snippet of text is <strong>rendered as bold text</strong>.</p>
</div>
<div class="highlight"><pre><code class="html"><span class="nt"><strong></span>rendered as bold text<span class="nt"></strong></span>
</code></pre></div>
<h3>Italics</h3>
<p>For emphasizing a snippet of text with italics.</p>
<div class="bs-example">
<p>The following snippet of text is <em>rendered as italicized text</em>.</p>
</div>
<div class="highlight"><pre><code class="html"><span class="nt"><em></span>rendered as italicized text<span class="nt"></em></span>
</code></pre></div>
<div class="bs-callout bs-callout-info">
<h4>Alternate elements</h4>
<p>Feel free to use <code><b></code> and <code><i></code> in HTML5. <code><b></code> is meant to highlight words or phrases without conveying additional importance while <code><i></code> is mostly for voice, technical terms, etc.</p>
</div>
<h3>Alignment classes</h3>
<p>Easily realign text to components with text alignment classes.</p>
<div class="bs-example">
<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>
</div>
<div class="highlight"><pre><code class="html"><span class="nt"><p</span> <span class="na">class=</span><span class="s">"text-left"</span><span class="nt">></span>Left aligned text.<span class="nt"></p></span>
<span class="nt"><p</span> <span class="na">class=</span><span class="s">"text-center"</span><span class="nt">></span>Center aligned text.<span class="nt"></p></span>
<span class="nt"><p</span> <span class="na">class=</span><span class="s">"text-right"</span><span class="nt">></span>Right aligned text.<span class="nt"></p></span>
<span class="nt"><p</span> <span class="na">class=</span><span class="s">"text-justify"</span><span class="nt">></span>Justified text.<span class="nt"></p></span>
</code></pre></div>
<!-- Abbreviations -->
<h2 id="type-abbreviations">Abbreviations</h2>
<p>Stylized implementation of HTML's <code><abbr></code> element for abbreviations and acronyms to show the expanded version on hover. Abbreviations with a <code>title</code> attribute have a light dotted bottom border and a help cursor on hover, providing additional context on hover.</p>
<h3>Basic abbreviation</h3>
<p>For expanded text on long hover of an abbreviation, include the <code>title</code> attribute with the <code><abbr></code> element.</p>
<div class="bs-example">
<p>An abbreviation of the word attribute is <abbr title="attribute">attr</abbr>.</p>
</div>
<div class="highlight"><pre><code class="html"><span class="nt"><abbr</span> <span class="na">title=</span><span class="s">"attribute"</span><span class="nt">></span>attr<span class="nt"></abbr></span>
</code></pre></div>
<h3>Initialism</h3>
<p>Add <code>.initialism</code> to an abbreviation for a slightly smaller font-size.</p>
<div class="bs-example">
<p><abbr title="HyperText Markup Language" class="initialism">HTML</abbr> is the best thing since sliced bread.</p>
</div>
<div class="highlight"><pre><code class="html"><span class="nt"><abbr</span> <span class="na">title=</span><span class="s">"HyperText Markup Language"</span> <span class="na">class=</span><span class="s">"initialism"</span><span class="nt">></span>HTML<span class="nt"></abbr></span>
