4 <p>Allow browsers to determine video or slideshow dimensions based on the width of their containing block by creating an intrinsic ratio that will properly scale on any device.</p>
5 <p>Rules are directly applied to <code><iframe></code>, <code><embed></code>, <code><video></code>, and <code><object></code> elements; optionally use an explicit descendant class <code>.embed-responsive-item</code> when you want to match the styling for other attributes.</p>
