Typewriter Text Hover
Hovering clears the line and types it back one character at a time behind a moving caret, which keeps blinking at the end. steps() on clip-path and on the caret keep both in sync.
Also known as: typewriter effect on hover, retype text animation, typing hover effect.

}Customizing this snippet
- Color: set
--hfx-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--hfx-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
