 ## Why not use pure CSS?
 
-CSS tooltips have accessibility and usability problems:
-
-- **Clipping and overflow issues**: CSS tooltips will not be prevented from
-  overflowing clipping boundaries, such as the viewport. The tooltip gets
-  partially cut off or overflows if it's near the edge since there is no dynamic
-  positioning logic. When using Popper, your tooltip will always be positioned
-  in the right place.
-- **No flipping**: CSS tooltips will not flip to a different placement to fit
-  better in view if necessary. Popper automatically flips the tooltip to make it
-  fit in view as best as possible for the user.
-- **Using HTML**: Popovers containing interactive HTML are difficult or not
