Sparkle Text Effect: CSS Text Animation

Sparkle Text Effect

Four-point stars pop and spin over a gradient word, one after another, like a magic label. Each star is a clip-path shape with its own position and negative delay set inline.

Also known as: twinkle text css, magic sparkle text, sparkling stars 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.
