Hover underline animation	animation	advanced	blog_images/coffee-phone-tray-2.jpg	2018-02-28T13:19:22+02:00	2021-10-11T18:44:51+03:00

Creates 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.

<p class="hover-underline-animation">Hover this text to see the effect!</p>
