<div class="bs-docs-section">
<div class="page-header">
<h1 id="overview">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 id="overview-doctype">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 %}
<!DOCTYPE html>
<html lang="en">
...
</html>
{% endhighlight %}
<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>
{% highlight html %}
<meta name="viewport" content="width=device-width, initial-scale=1.0">
{% endhighlight %}
<h3 id="overview-responsive-images">Responsive images</h3>
<p>Images in Bootstrap 3 can be made responsive-friendly via the addition of the <code>.img-responsive</code> class. This applies <code>max-width: 100%;</code> and <code>height: auto;</code> to the image so that it scales nicely to the parent element.</p>
{% highlight html %}
<img src="..." class="img-responsive" alt="Responsive image">
{% endhighlight %}
<h3 id="overview-type-links">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 <code>scaffolding.less</code>.</p>
<h3 id="overview-normalize">Normalize reset</h3>
<p>For improved cross-browser rendering, we use <a href="http://necolas.github.io/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>
<h3 id="overview-container">Centering with container</h3>
<p>Easily center a page's contents by wrapping its contents in a <code>.container</code>. Containers set <code>max-width</code> at various media query breakpoints to match our grid system.</p>
{% highlight html %}

</div>
<p class="lead">With the launch of Bootstrap 3, icons have been moved to a <a href="https://github.com/twbs/bootstrap-glyphicons">separate repository</a>. This keeps the primary project as lean as possible, makes it easier for folks to swap icon libraries, and makes Glyphicons icon fonts more readily available to more people outside Bootstrap.</p>

<!-- Grid system
================================================== -->
<div class="bs-docs-section">
<div class="page-header">
<h1 id="grid">Grid system</h1>
</div>
<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-media-queries">Media queries</h3>
<p>We use the following media queries to create the key breakpoints in our grid system.</p>
{% highlight css %}
/* Extra small devices (phones, up to 480px) */
/* No media query since this is the default in Bootstrap */
/* Small devices (tablets, 768px and up) */
@media (min-width: @screen-tablet) { ... }
/* Medium devices (tablets, 992px and up) */
@media (min-width: @screen-desktop) { ... }
/* Large devices (large desktops, 1200px and up) */
@media (min-width: @screen-large-desktop) { ... }
{% endhighlight %}
<p>We occasionally expand on these media queries to include a <code>max-width</code> to limit CSS to a narrower set of devices.</p>
{% highlight css %}
@media (max-width: @screen-phone-max) { ... }
@media (min-width: @screen-tablet) and (max-width: @screen-tablet-max) { ... }
@media (min-width: @screen-desktop) and (max-width: @screen-desktop-max) { ... }
@media (min-width: @screen-large-desktop) { ... }

<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.</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>
{% highlight css %}
@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 %}
// Creates a wrapper for a series of columns
.make-row(@gutter: @grid-gutter-width) {
// Then clear the floated columns
.clearfix();

margin-right: (@gutter / -2);
}
// Negative margin nested rows out to align the content of columns
.row {

margin-right: (@gutter / -2);
}
}
// Generate the extra small columns
.make-xs-column(@columns; @gutter: @grid-gutter-width) {
position: relative;
// Prevent columns from collapsing when empty
min-height: 1px;
// Inner gutter via padding
padding-left: (@gutter / 2);
padding-right: (@gutter / 2);
// Calculate width based on number of columns available
@media (min-width: @grid-float-breakpoint) {
float: left;
width: percentage((@columns / @grid-columns));

}
}
.make-sm-column-pull(@columns) {
@media (min-width: @screen-small) {

// Prevent columns from collapsing when empty
min-height: 1px;
// Inner gutter via padding

// Generate the large column offsets
.make-md-column-offset(@columns) {
@media (min-width: @screen-medium) {
margin-left: percentage((@columns / @grid-columns));
}
}
.make-md-column-push(@columns) {

}
}
.make-md-column-pull(@columns) {
@media (min-width: @screen-medium) {

}
}
{% 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 %}
.wrapper {
.make-row();
}
.content-main {
.make-lg-column(8);
}
.content-secondary {
.make-lg-column(3);
.make-lg-column-offset(1);

<!-- Body copy -->
<h2 id="type-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>1.428</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 computed line-height (10px by default).</p>
<div class="bs-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>
{% highlight html %}
<p>...</p>
{% endhighlight %}
<!-- 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>
{% highlight html %}
<p class="lead">...</p>
{% endhighlight %}
<!-- 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>
<div class="bs-example">
<p><small>This line of text is meant to be treated as fine print.</small></p>
</div>
{% highlight html %}
<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-example">
<p>The following snippet of text is <strong>rendered as bold text</strong>.</p>
</div>
{% highlight html %}
<strong>rendered as bold text</strong>
{% endhighlight %}
<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>
{% highlight html %}
<em>rendered as italicized text</em>
{% endhighlight %}
<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>
</div>
{% highlight html %}
<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-example">
<p class="text-muted">Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.</p>
<p class="text-primary">Nullam id dolor id nibh ultricies vehicula ut id elit.</p>

<!-- 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>
{% highlight html %}
<abbr title="attribute">attr</abbr>
{% endhighlight %}
<h3>Initialism</h3>
<p>Add <code>.initialism</code> to an abbreviation for a slightly smaller font-size.</p>

<p>Remove the default <code>list-style</code> and left margin on list items (immediate children only). <strong>This only applies to immediate children list items</strong>, meaning you will need to add the class for any nested lists as well.</p>
<div class="bs-example">
<ul class="list-unstyled">
<li>Lorem ipsum dolor sit amet</li>
<li>Consectetur adipiscing elit</li>
<li>Integer molestie lorem at massa</li>
<li>Facilisis in pretium nisl aliquet</li>
<li>Nulla volutpat aliquam velit
<ul>
<li>Phasellus iaculis neque</li>
<li>Purus sodales ultricies</li>
<li>Vestibulum laoreet porttitor sem</li>
<li>Ac tristique libero volutpat at</li>
</ul>
</li>
<li>Faucibus porta lacus fringilla vel</li>
<li>Aenean sit amet erat nunc</li>
<li>Eget porttitor lorem</li>
</ul>
</div>
{% highlight html %}
<ul class="list-unstyled">
<li>...</li>
</ul>
{% endhighlight %}
<h3>Inline</h3>
<p>Place all list items on a single line with <code>inline-block</code> and some light padding.</p>
<div class="bs-example">
<ul class="list-inline">
<li>Lorem ipsum</li>
<li>Phasellus iaculis</li>
<li>Nulla volutpat</li>
</ul>
</div>
{% highlight html %}
<ul class="list-inline">
<li>...</li>
</ul>
{% endhighlight %}
<h3>Description</h3>
<p>A list of terms with their associated descriptions.</p>
<div class="bs-example">
<dl>
<dt>Description lists</dt>
<dd>A description list is perfect for defining terms.</dd>
<dt>Euismod</dt>
<dd>Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.</dd>
<dd>Donec id elit non mi porta gravida at eget metus.</dd>
<dt>Malesuada porta</dt>
<dd>Etiam porta sem malesuada magna mollis euismod.</dd>
</dl>
</div>
{% highlight html %}
<dl>
<dt>...</dt>
<dd>...</dd>
</dl>
{% endhighlight %}
<h4>Horizontal description</h4>
<p>Make terms and descriptions in <code><dl></code> line up side-by-side. Starts off stacked like default <code><dl></code>s, but when the navbar expands, so do these.</p>
<div class="bs-example">
<dl class="dl-horizontal">
<dt>Description lists</dt>
<dd>A description list is perfect for defining terms.</dd>
<dt>Euismod</dt>
<dd>Vestibulum id ligula porta felis euismod semper eget lacinia odio sem nec elit.</dd>
<dd>Donec id elit non mi porta gravida at eget metus.</dd>
<dt>Malesuada porta</dt>
<dd>Etiam porta sem malesuada magna mollis euismod.</dd>
<dt>Felis euismod semper eget lacinia</dt>
<dd>Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</dd>
</dl>
</div>
{% highlight html %}
<dl class="dl-horizontal">
<dt>...</dt>
<dd>...</dd>
</dl>
{% endhighlight %}
<div class="bs-callout bs-callout-info">
<h4>Auto-truncating</h4>
<p>Horizontal description lists will truncate terms that are too long to fit in the left column with <code>text-overflow</code>. In narrower viewports, they will change to the default stacked layout.</p>
