          <h3>Requires 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>

{% 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>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>

          <p>Bootstrap's global default <code>font-size</code> is <strong>14px</strong>, with a <code>line-height</code> of <strong>20px</strong>. This is applied to the <code>&lt;body&gt;</code> and all paragraphs. In addition, <code>&lt;p&gt;</code> (paragraphs) receive a bottom margin of half their line-height (10px by default).</p>

          <!-- 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="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></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 %}

{% 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">

          <h3>Emphasis classes</h3>
          <p>Convey meaning through color with a handful of emphasis utility classes.</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>

        <!-- Grid system

            <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>.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>

          <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);
}
