Hover underline animation	animation,advanced	2018-02-28T13:19:22+02:00	2020-12-30T15:37:37+02:00

Creates an animated underline effect when the text is hovered over.

• Use display: inline-block to prevent the underline from spanning the entire parent width rather than just the text content.
• Use the :after pseudo-element with a width of 100% and position: absolute, placing 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.

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