Slice Glitch Text Effect
The word tears along a horizontal line and the two halves jump sideways, then snap back together. Two clip-path halves of the same text move apart, so there is never a doubled copy.
Also known as: glitch text tear, clip path glitch, sliced text css.

}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.
