Navigation list item hover and focus effect	visual	beginner	2019-09-19 22:48:57 +0300	2021-10-11 18:44:51 +0300

Creates a custom hover and focus effect for navigation items, using CSS transformations.

• 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-class selectors to transition the pseudo-element to transform: scale(1) and show its colored background.
• Prevent the pseudo-element from covering the anchor element by using z-index.

<nav class="hover-nav">
  <ul>
    <li><a href="#">Home</a></li>
    <li><a href="#">About</a></li>
    <li><a href="#">Contact</a></li>
  </ul>
</nav>
