Crossword Cells Check

Four crossword cells beside a clue. Checking drops D, O, N and E into the cells one after another, each with a small ink press, and the clue number turns the accent. Unchecking erases right to left.

Also known as: crossword checkbox, letter tiles checkbox animation, word puzzle checkbox css, done letters animation.

Customizing this snippet

  • Color: set --chk-color on the element or a parent. Currently previewing #3b82f6.
  • Size: set --chk-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 24px.
  • 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.
