This CodePen demonstrates how we can animate the opening and closing states of an accordion with fancy reveal animation using only CSS. This concept is suitable for creating FAQ sections, Table of Contents, and more.

We cannot transition height or any CSS property from zero to auto. If we want to smoothly expand a collapsed accordion, we could set a max-height and transition the height property to a large value when we expand the section. However, it may not properly work if the content is larger than the max-height.

Since the accordion's title is an anchor element, users can also navigate through the items with their keyboard.

I would highly recommend watching his video, where he beautifully explains the technique and points out how he discovered it. Also, read Keith J. Grant's post and Nelson Menezes's post on the same topic.
