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.
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 html %}
Aspect ratios can be customized with modifier classes.
{% highlight html %}
These utility classes float an element to the left or right, or disable floating, based on the current viewport size using the CSS float property. !important is included to avoid specificity issues. These use the same viewport width breakpoints as the grid system.
Two similar non-responsive Sass mixins (float-left and float-right) are also available.
{% example html %}
{% endexample %}
{% highlight scss %} // Related simple non-responsive mixins .element { @include float-left; } .another-element { @include float-right; } {% endhighlight %}
