-## Responsive embeds
+## 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.
+
 {% example html %}
 <div class="embed-responsive embed-responsive-16by9">
   <iframe class="embed-responsive-item" src="https://www.youtube.com/embed/zpOULjyy-n8?rel=0" allowfullscreen></iframe>
 </div>
 {% endexample %}
 
+## Aspect ratios
+
 Aspect ratios can be customized with modifier classes.

-## Responsive floats
-
-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](https://developer.mozilla.org/en-US/docs/Web/CSS/float). `!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 %}
-<div class="float-left">Float left on all viewport sizes</div><br>
-<div class="float-right">Float right on all viewport sizes</div><br>
-<div class="float-none">Don't float on all viewport sizes</div><br>
-
-<div class="float-sm-left">Float left on viewports sized SM (small) or wider</div><br>
-<div class="float-md-left">Float left on viewports sized MD (medium) or wider</div><br>
-<div class="float-lg-left">Float left on viewports sized LG (large) or wider</div><br>
-<div class="float-xl-left">Float left on viewports sized XL (extra-large) or wider</div><br>

+title: Float
+description: Toggle floats on any element, across any breakpoint, using our responsive float utilities.
+group: utilities
+toc: true
+---
+
+## Overview
+
+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](https://developer.mozilla.org/en-US/docs/Web/CSS/float). `!important` is included to avoid specificity issues. These use the same viewport breakpoints as our grid system.
+
+## Classes
+
+Toggle a float with a class:
+
+{% example html %}
+<div class="float-left">Float left on all viewport sizes</div><br>
+<div class="float-right">Float right on all viewport sizes</div><br>
+<div class="float-none">Don't float on all viewport sizes</div>
+{% endexample %}
+
+## Mixins
+
+Or by Sass mixin:
+
+{% highlight scss %}
+.element {
+  @include float-left;
+}
+.another-element {
+  @include float-right;
+}
+.one-more {
+  @include float-none;
+}
+{% endhighlight %}
+
+## Responsive
+
+Responsive variations also exist for each `float` value.
+
+{% example html %}
+<div class="float-sm-left">Float left on viewports sized SM (small) or wider</div><br>
+<div class="float-md-left">Float left on viewports sized MD (medium) or wider</div><br>
+<div class="float-lg-left">Float left on viewports sized LG (large) or wider</div><br>
+<div class="float-xl-left">Float left on viewports sized XL (extra-large) or wider</div><br>
+{% endexample %}
+
+Here are all the support classes;
+
+{% for bp in site.data.breakpoints %}
+- `.float{{ bp.abbr }}-left`
+- `.float{{ bp.abbr }}-right`
+- `.float{{ bp.abbr }}-none`{% endfor %}
