      <h1>Getting started</h1>
    </div>
    <p class="lead">There are a few easy ways to quickly get started with Bootstrap, each one appealing to a different skill level and use case. Read through to see what suits your particular needs.</p>
    <div class="row">
      <div class="col-span-6">
        <h3>Compiled CSS and JS</h3>
        <p><strong>The fastest way to get started:</strong> get the compiled and minified versions of our CSS, JavaScript, and fonts. No documentation or original source files are included.</p>
        <p><a class="btn btn-large btn-primary" href="assets/bootstrap.zip" onclick="_gaq.push(['_trackEvent', 'Getting started', 'Download', 'Download compiled']);">Download Bootstrap</a></p>

      <div class="col-span-6">
        <h3>Latest source code</h3>
        <p>Get the original files for all CSS and JavaScript, along with a local copy of the docs by downloading the latest version directly from GitHub.</p>
        <p><a class="btn btn-large" href="https://github.com/twitter/bootstrap/zipball/master" onclick="_gaq.push(['_trackEvent', 'Getting started', 'Download', 'Download source']);">Download Bootstrap source</a></p>
      </div>
      <div class="col-span-6">
        <h3>Clone or fork via GitHub</h3>
        <p>Clone the entire project or fork your own version of Bootstrap to make it your own by visiting us on GitHub.</p>
        <p><a class="btn btn-large" href="https://github.com/twitter/bootstrap/" onclick="_gaq.push(['_trackEvent', 'Getting started', 'Download', 'GitHub project']);">GitHub repository</a></p>
      </div>
      <div class="col-span-6">
        <h3>Bower</h3>
        <p>Install and manage the original files for all CSS and JavaScript, along with a local copy of the docs, using <a href="http://twitter.github.com/bower">Bower</a>.</p>
        {% highlight bash %}$ bower install bootstrap{% endhighlight %}

  <!-- File structure
  ================================================== -->
  <div class="bs-docs-section" id="whats-included">
    <div class="page-header">
      <h1>What's included</h1>
    </div>
    <p class="lead">Within the download you'll find the following directories and files, logically grouping common assets and providing both compiled and minified variations.</p>
    <p>Once downloaded, unzip the compressed folder to see the structure of (the compiled) Bootstrap. You'll see something like this:</p>

{% highlight bash %}
  bootstrap/
  ├── css/
  │   ├── bootstrap.css
  │   ├── bootstrap.min.css
  ├── js/
  │   ├── bootstrap.js

      └── glyphiconshalflings-regular.woff
{% endhighlight %}

    <p>This is the most basic form of Bootstrap: compiled files for quick drop-in usage in nearly any web project. We provide compiled CSS and JS (<code>bootstrap.*</code>), as well as compiled and minified CSS and JS (<code>bootstrap.min.*</code>). The image files are compressed using <a href="http://imageoptim.com/">ImageOptim</a>, a Mac app for compressing PNGs.</p>
    <p>Please note that <strong>all JavaScript plugins require jQuery</strong> to be included.</p>

      <h1>Overview</h1>
    </div>
    <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>HTML5 doctype required</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>
{% highlight html linenos %}
<!DOCTYPE html>
<html lang="en">
  ...
</html>
{% endhighlight %}

    <h3>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>&lt;head&gt;</code>.</p>
{% highlight html linenos %}
<meta name="viewport" content="width=device-width, initial-scale=1.0">
{% endhighlight %}

    <h3>Responsive images</h3>
    <p>We automatically attempt to scale images to appropriate sizes with a global <code>max-width: 100%;</code> on all <code>&lt;img&gt;</code> elements. If you run into problems (e.g., with Google Maps), be sure to disable this property on a per-case basis.</p>

    <h3>Typography and links</h3>
    <p>Bootstrap sets basic global display, typography, and link styles. Specifically, we:</p>
    <ul>
      <li>Remove <code>margin</code> on the body</li>
      <li>Set <code>background-color: white;</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 <strong>scaffolding.less</strong>.</p>

    <h3>Normalize reset</h3>
    <p>For improved cross-browser rendering, we use <a href="http://necolas.github.com/normalize.css/" target="_blank">Normalize</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>

  <!-- Grid system
  ================================================== -->
  <div class="bs-docs-section" id="grid">
    <div class="page-header">
      <h1>Grid system</h1>
    </div>
    <p class="lead">Bootstrap includes a responsive, percent-based grid system that appropriately scales up to 12 columns as the device or viewport size increases&mdash;in other words, it's mobile first. It includes <a href="#grid-example">predefined classes</a> for this, as well as powerful <a href="#grid-less">mixins for generating semantic layouts</a>.</p>

    <h3 id="grid-example">Grid example</h3>
    <p>On mobile devices, the grid starts out stacked. Above 768px, it becomes horizontal as media queries kick in to apply <code>float</code>s and <code>width</code>s. To create a basic grid layout, wrap a series of <code>.col-span-*</code> elements within a <code>.row</code>. As this is a 12-column grid, each <code>.span*</code> spans a number of those 12 columns, and should always add up to 12 for each row (or the number of columns in the parent), even at mobile resolutions.</p>
    <div class="bs-docs-grid">
      <div class="row show-grid">
        <div class="col-span-1">1</div>

    <h3 id="grid-offsetting">Offsetting columns</h3>
    <p>Move columns to the right using <code>.col-offset-*</code> classes. Each class increases the left margin of a column by a whole column. For example, <code>.col-offset-4</code> moves <code>.col-span-4</code> over four columns.</p>

</div>
{% endhighlight %}

    <h3 id="grid-less">LESS mixins and variables</h3>
    <p>In addition to <a href="#grid-example">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>
{% highlight css linenos %}
@grid-columns:              12;
@grid-gutter-width:         30px;
@grid-float-breakpoint:     768px;
{% endhighlight %}

    <h4>Mixins</h4>
    <p>Mixins are used in conjunction with the grid variables to generate semantic CSS for individual grid columns.</p>
{% highlight css linenos %}
// Creates a wrapper for a series of columns
.make-row() {
  // Negative margin the row out to align the content of columns
  margin-left:  (@grid-gutter-width / -2);
  margin-right: (@grid-gutter-width / -2);
  // Then clear the floated columns
  .clear_float();
}

// Generate the columns
.make-column(@columns) {
  @media (min-width: @grid-float-breakpoint) {
    float: left;
    // Calculate width based on number of columns available
    width: percentage(@columns / @grid-columns);
  }
  // Prevent columns from collapsing when empty
  min-height: 1px;
  // Set inner padding as gutters instead of margin
  padding-left:  (@grid-gutter-width / 2);
  padding-right: (@grid-gutter-width / 2);
}

// Generate the column offsets
.make-column-offset(@columns) {
  @media (min-width: @grid-float-breakpoint) {
    margin-left: percentage((@columns / @grid-columns));
  }
}
{% endhighlight %}

    <h4>Example usage</h4>
    <p>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.</p>
{% highlight css linenos %}
.wrapper {
  .make-row();
}
.content-main {
  .make-column(8);
}
.content-secondary {
  .make-column(3);
  .make-column-offset(1);
}
{% endhighlight %}
{% highlight html linenos %}
<div class="wrapper">
  <div class="content-main">...</div>
  <div class="content-secondary">...</div>
</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, <small>use the small tag</small> to set text at 85% the size of the parent. Heading elements receive their own <code>font-size</code> for nested <code>&lt;small&lt;</code> elements.</p>
    <div class="bs-docs-example">
      <p><small>This line of text is meant to be treated as fine print.</small></p>
    </div>
{% highlight html linenos %}
<small>This line of text is meant to be treated as fine print.</small>
{% endhighlight %}


    <h3>Bold</h3>
    <p>For emphasizing a snippet of text with a heavier font-weight.</p>
    <div class="bs-docs-example">
      <p>The following snippet of text is <strong>rendered as bold text</strong>.</p>
    </div>
{% highlight html linenos %}
<strong>rendered as bold text</strong>
{% endhighlight %}

    <h3>Italics</h3>
    <p>For emphasizing a snippet of text with italics.</p>
    <div class="bs-docs-example">
      <p>The following snippet of text is <em>rendered as italicized text</em>.</p>
    </div>
{% highlight html linenos %}
<em>rendered as italicized text</em>
{% endhighlight %}

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

    <h3>Alignment classes</h3>
    <p>Easily realign text to components with text alignment classes.</p>
    <div class="bs-docs-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>
    </div>
{% highlight html linenos %}
<p class="text-left">Left aligned text.</p>
<p class="text-center">Center aligned text.</p>
<p class="text-right">Right aligned text.</p>
{% endhighlight %}

    <h3>Emphasis classes</h3>
    <p>Convey meaning through color with a handful of emphasis utility classes.</p>
    <div class="bs-docs-example">
      <p class="text-muted">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>
      <p class="text-warning">Etiam porta sem malesuada magna mollis euismod.</p>
      <p class="text-error">Donec ullamcorper nulla non metus auctor fringilla.</p>
      <p class="text-success">Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>
    </div>
{% highlight html linenos %}
<p class="text-muted">...</p>
<p class="text-warning">...</p>
<p class="text-error">...</p>
<p class="text-success">...</p>
{% endhighlight %}


    <!-- Abbreviations -->
    <h2 id="type-abbreviations">Abbreviations</h2>
    <p>Stylized implementation of HTML's <code>&lt;abbr&gt;</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>&lt;abbr&gt;</code> element.</p>
    <div class="bs-docs-example">
      <p>An abbreviation of the word attribute is <abbr title="attribute">attr</abbr>.</p>
    </div>
{% highlight html linenos %}
<abbr title="attribute">attr</abbr>
{% endhighlight %}

    <h3>Initialism</h3>

    <h2 id="type-addresses">Addresses</h2>
    <p>Present contact information for the nearest ancestor or the entire body of work. Preserve formatting by ending all lines with <code>&lt;br&gt;</code>.</p>
    <div class="bs-docs-example">
