Every now and then I wish I could style child elements from their parent instead of repeating class names over and over again. Then I remember that this is actually possible with more recent versions of Tailwind!
Here's an example using a description list element.
<dl className="[&>dt]:font-semibold [&>dd]:mb-2">
<dt>Some term</dt>
<dd>The description.</dd>
<dt>Some other term</dt>
<dd>The description for that other term.</dd>
</dl>
One thing I should note is that the more common approach for handling this is to break out the dt / dd part to a separate component in your favorite framework. That way you can have the class names on the dt / dd elements while still avoiding unnecessary repetition. For simple cases, like the above description list, it feels like overkill to refactor your code to use a separate component though.
