<h2 id="about">About</h2>
<p>Rules are directly applied to <code class="highlighter-rouge">&lt;iframe&gt;</code>, <code class="highlighter-rouge">&lt;embed&gt;</code>, <code class="highlighter-rouge">&lt;video&gt;</code>, and <code class="highlighter-rouge">&lt;object&gt;</code> elements; optionally use an explicit descendant class <code class="highlighter-rouge">.embed-responsive-item</code> when you want to match the styling for other attributes.</p>
<p><strong>Pro-Tip!</strong> You dont need to include <code class="highlighter-rouge">frameborder="0"</code> in your <code class="highlighter-rouge">&lt;iframe&gt;</code>s as we override that for you.</p>
<h2 id="example">Example</h2>
<p>Wrap any embed like an <code class="highlighter-rouge">&lt;iframe&gt;</code> in a parent element with <code class="highlighter-rouge">.embed-responsive</code> and an aspect ratio. The <code class="highlighter-rouge">.embed-responsive-item</code> isnt strictly required, but we encourage it.</p>
