Brush Stroke Underline
A tapered brush swoosh paints itself under a word, heavy where the brush lands and thinning to a point. A filled SVG shape stretched to the word's width and uncovered with clip-path.
Also known as: paint brush underline css, hand drawn swoosh underline, tapered underline svg.

}Customizing this snippet
- Color: set
--txt-coloron the element or a parent. Currently previewing#3b82f6. - Font size: set
--txt-size. Every other dimension is inem, so the whole thing scales together. Currently previewing40px. - 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.
