- `.collapsing` is applied during transitions
- `.collapse.show` shows content
-You can use a link with the `href` attribute, or a button with the `data-target` attribute. In both cases, the `data-toggle="collapse"` is required.
+Generally, we recommend using a button with the `data-target` attribute. While not recommended from a semantic point of view, you can also use a link with the `href` attribute (and a `role="button"`). In both cases, the `data-toggle="collapse"` is required.
