Color Wipe Repaint Text

Fresh coats of color roll across the word one after another, each with a soft wet edge, and the cycle never shows a seam. Three stacked copies with a moving mask, and z-index steps hand over the top.

Also known as: text color change animation, color wipe text css, paint text animation.

Customizing this snippet

  • Color: set --txt-color on the element or a parent. Currently previewing #3b82f6.
  • Font size: set --txt-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 40px.
  • Speed: change the duration on the transition or animation shorthand. 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.
