Text Rise From Underline Effect

An underline draws itself first, then the text rises out from behind it with a small overshoot. The wrapper's overflow: hidden ends at the line, so the text appears to come out of it.

Also known as: text reveal from line, underline then text animation, rise from behind line.

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.
