HTML-CSS : Exercise-3 with Solution

Using HTML, CSS create display an image overlay effect on hover.

  • Use the :before and :after pseudo-elements for the top and bottom bars of the overlay respectively. Set their opacity, transform and transition to produce the desired effect.
  • Use the <figcaption> for the text of the overlay. Set display: flex, flex-direction: column and justify-content: center to center the text into the image.
  • Use the :hover pseudo-selector to update the opacity and transform of all the elements and display the overlay.
