 ### Horizontal description
 
-Make terms and descriptions in `<dl>` line up side-by-side. Starts off stacked like default `<dl>`s, but when the navbar expands, so do these.
+Align terms and descriptions horizontally by using our grid system's predefined classes (or semantic mixins). For longer terms, you can optionally add a `.text-truncate` class to truncate the text with an ellipsis.
