Beam Lit Headline

A comet of light runs along a hairline under the word. Each letter it passes lights up from below with a soft floor glow, and the letters stay lit until they dim together.

Also known as: light beam under text, glowing line text reveal, linear style hero text, uplit headline 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.
