About

Rules are directly applied to <iframe>, <embed>, <video>, and <object> elements; optionally use an explicit descendant class .embed-responsive-item when you want to match the styling for other attributes.

Pro-Tip! You don't need to include frameborder="0" in your <iframe>s as we override that for you.

Example

Wrap any embed like an <iframe> in a parent element with .embed-responsive and an aspect ratio. The .embed-responsive-item isn't strictly required, but we encourage it.

{% capture example %}

{% endcapture %} {% include example.html content=example %}

Aspect ratios

Aspect ratios can be customized with modifier classes. By default the following ratio classes are provided:

{% highlight html %}

{% endhighlight %}

Within _variables.scss, you can change the aspect ratios you want to use. Here's an example of the $embed-responsive-aspect-ratios list:

{% highlight scss %} $embed-responsive-aspect-ratios: ( (21 9), (16 9), (4 3), (1 1) ) !default; {% endhighlight %}
