 ## About
 
-Rules are directly applied to `<iframe>`, `<embed>`, `<video>`, and `<object>` elements. You can also use an explicit use an explicit descendant class, `.ratio-item`, when you want to match the styling for other attributes. Aspect ratios are declared in a Sass map and included in each class via CSS variable, which also allows [custom aspect ratios](#custom-ratios).
+Use the ratio helper to manage the aspect ratios of external content like `<iframe>`s, `<embed>`s, `<video>`s, and `<object>`s. These helpers also can be used on any standard HTML child element (e.g., a `<div>` or `<img>`). Styles are applied from the parent `.ratio` class directly to the child.

 **Pro-Tip!** You don't need `frameborder="0"` on your `<iframe>`s as we override that for you in [Reboot]({{< docsref "/content/reboot" >}}).

 - Responsive embed helpers have been renamed to [ratio helpers]({{< docsref "/helpers/ratio" >}}) with new class names and improved behaviors, as well as a helpful CSS variable.
   - Classes have been renamed to change `by` to `x` in the aspect ratrio. For example, `.ratio-16by9` is now `.ratio-16x9`.
+  - We've dropped the `.embed-responsive-item` and element group selector in favor of a simpler `.ratio > *` selector. No more class needed, and the ratio helper now works with any HTML element.
   - The `$embed-responsive-aspect-ratios` Sass map has been renamed to `$aspect-ratios` and its values have been simplified to include the class name and the percentage as the `key: value` pair.
   - CSS variables are now generated and included for each value in the Sass map. Modify the `--aspect-ratio` variable on the `.ratio` to create any [custom aspect ratio]({{< docsref "/helpers/ratio#custom-ratios" >}}).
