Lava Text Effect

Glowing molten letters with dark crust drifting across them in two layers, so cracks of bright orange open and close. Crust patches are tiled radial gradients moving in opposite directions.

Also known as: molten text css, magma text effect, lava lamp text.

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.
