Underline to Strikethrough Hover
A thick underline slides up through the word and becomes a strikethrough while the text fades, like ticking off a to-do. One pseudo-element moves on translateY; nothing is redrawn.
Also known as: strikethrough on hover, underline moves to line through, cross out text hover.

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.
