|

|

<p>Assign responsive-friendly <code class="highlighter-rouge">margin</code> or <code class="highlighter-rouge">padding</code> values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from <code class="highlighter-rouge">.25rem</code> to <code class="highlighter-rouge">3rem</code>.</p>
|

|
||
<h2 id="notation">Notation</h2>
|
||
|
||
<p>Spacing utilities that apply to all breakpoints, from <code class="highlighter-rouge">xs</code> to <code class="highlighter-rouge">xl</code>, have no breakpoint abbreviation in them. This is because those classes are applied from <code class="highlighter-rouge">min-width: 0</code> and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.</p>
|
||
|
||
<p>The classes are named using the format <code class="highlighter-rouge">{property}{sides}-{size}</code> for <code class="highlighter-rouge">xs</code> and <code class="highlighter-rouge">{property}{sides}-{breakpoint}-{size}</code> for <code class="highlighter-rouge">sm</code>, <code class="highlighter-rouge">md</code>, <code class="highlighter-rouge">lg</code>, and <code class="highlighter-rouge">xl</code>.</p>

<p>Additionally, Bootstrap also includes an <code class="highlighter-rouge">.mx-auto</code> class for horizontally centering fixed-width block level content—that is, content that has <code class="highlighter-rouge">display: block</code> and a <code class="highlighter-rouge">width</code> set—by setting the horizontal margins to <code class="highlighter-rouge">auto</code>.</p>
