Demo
Explanation
  • Use the ::before pseudo-element at the list item anchor to create a hover effect, hide it using transform: scale(0).
  • Use the :hover and :focus pseudo-selectors to transition to transform: scale(1) and show the pseudo-element with its colored background.
  • Prevent the pseudo-element from covering the anchor element by using z-index: -1.
