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.
