<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>
<pre class="prettyprint linenums">

<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>

<h2>Live grid example</h2>
<p>The default Bootstrap grid system utilizes <strong>12 columns</strong>, making for a 940px wide container without <a href="./scaffolding.html#responsive">responsive features</a> enabled. With the responsive CSS file added, the grid adapts to be 724px and 1170px wide depending on your viewport. Below 767px viewports, the columns become fluid and stack vertically.</p>

<div class="row show-grid">
<div class="span12">12</div>
</div>
</div>
<h3>Basic grid HTML</h3>
<p>For a simple two column layout, create a <code>.row</code> and add the appropriate number of <code>.span*</code> columns. 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).</p>
<pre class="prettyprint linenums">
<div class="row">
<div class="span4">...</div>
<div class="span8">...</div>
</div>
</pre>
<p>Given this example, we have <code>.span4</code> and <code>.span8</code>, making for 12 total columns and a complete row.</p>
<h2>Offsetting columns</h2>
<p>Move columns to the right using <code>.offset*</code> classes. Each class increases the left margin of a column by a whole column. For example, <code>.offset4</code> moves <code>.span4</code> over four columns.</p>
<div class="bs-docs-grid">
<div class="row show-grid">
<div class="span4">4</div>
<div class="span4 offset4">4 offset 4</div>
</div><!-- /row -->
<div class="row show-grid">
<div class="span3 offset3">3 offset 3</div>
<div class="span3 offset3">3 offset 3</div>
</div><!-- /row -->
<div class="row show-grid">
<div class="span6 offset6">6 offset 6</div>
</div><!-- /row -->
</div>
<pre class="prettyprint linenums">
<div class="row">
<div class="span4">...</div>
<div class="span4 offset4">...</div>
</div>
</pre>
<h2>Nesting columns</h2>
<p>To nest your content with the default grid, add a new <code>.row</code> and set of <code>.span*</code> columns within an existing <code>.span*</code> column. Nested rows should include a set of columns that add up to the number of columns of its parent.</p>
<div class="row show-grid">
<div class="span9">

<!-- Typography
================================================== -->
<section id="typography">
<div class="page-header">
<h1>Typography</h1>
</div>
<h2 id="headings">Headings</h2>
<p>All HTML headings, <code><h1></code> through <code><h6></code> are available.</p>
<div class="bs-docs-example">
<h1>h1. Heading 1</h1>
<h2>h2. Heading 2</h2>
<h3>h3. Heading 3</h3>
<h4>h4. Heading 4</h4>
<h5>h5. Heading 5</h5>
<h6>h6. Heading 6</h6>
</div>
<h2 id="body-copy">Body copy</h2>
<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><body></code> and all paragraphs. In addition, <code><p></code> (paragraphs) receive a bottom margin of half their line-height (10px by default).</p>
<div class="bs-docs-example">
<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>
<pre class="prettyprint"><p>...</p></pre>
<h3>Lead body copy</h3>
<p>Make a paragraph stand out by adding <code>.lead</code>.</p>
<div class="bs-docs-example">
<p class="lead">Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus.</p>
</div>
<pre class="prettyprint"><p class="lead">...</p></pre>
<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>
<hr class="bs-docs-separator">
<h2 id="emphasis">Emphasis</h2>
<p>Make use of HTML's default emphasis tags with lightweight styles.</p>

<h3><code><small></code></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>
<pre class="prettyprint">
<p>
<small>This line of text is meant to be treated as fine print.</small>

<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>
<pre class="prettyprint"><strong>rendered as bold text</strong></pre>
<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>
<pre class="prettyprint"><em>rendered as italicized text</em></pre>
<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>
<h3>Emphasis classes</h3>
<p>Convey meaning through color with a handful of emphasis utility classes.</p>
<div class="bs-docs-example">

<h2 id="abbreviations">Abbreviations</h2>
