Strikethrough Typing Effect
Types a claim, pauses, strikes through the wrong word and types the right one after it, a copywriting move for hero lines. The strike is a scaled line; the retyped word picks up the accent.
Also known as: typing with strikethrough, cross out and retype text, typed correction effect.

}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.
