Edge-Lit Acrylic Sign

A clear acrylic sign in a lit base. A pulse of light climbs the slab from its bottom edge, lighting only the engraving as it passes and flaring the top edge, then the word holds a steady glow.

Also known as: edge lit acrylic css, engraved glass sign glow, led acrylic sign css, total internal reflection css.

Customizing this snippet

  • Color: set --gls-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --gls-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
  • 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.
