<p>The <code>.image</code> container will usually take up the <strong>whole width</strong> while maintaining the perfect ratio.
<br>If it doesn't, you can force it by appending the <code>is-fullwidth</code> modifier.</p>

<p>
You can apply a specific <strong>ratio</strong> on <strong>any element</strong> other than an <code>img</code>, simply by applying the <code>.has-ratio</code> modifier to a resizable element.
</p>
<p>
For example, you can apply a <code>16by9</code> ratio on an <code>iframe</code>. Resize the browser, and you'll see how the ratio is maintained.
