HTML-CSS: Hover underline animation

HTML-CSS : Exercise-15 with Solution

Using HTML, CSS create an animated underline effect when the user hovers over the text.

  • Use display: inline-block to make the underline span just the width of the text content.
  • Use the :after pseudo-element with width: 100% and position: absolute to place it below the content.
  • Use transform: scaleX(0) to initially hide the pseudo-element.
  • Use the :hover pseudo-class selector to apply transform: scaleX(1) and display the pseudo-element on hover.
  • Animate transform using transform-origin: left and an appropriate transition.
  • Remove the transform-origin property to make the transform originate from the center of the element.
