Sketchy Outline Text
Pencil-hatched letters with two loose outlines that never sit still, the 'line boil' of hand-drawn animation. Three stacked copies jump between poses with steps(1), so nothing tweens.
Also known as: hand drawn text effect css, line boil animation, pencil sketch text.

}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.
