Color Morph Gradient Text: CSS Text Animation

Color Morph Gradient Text

The two ends of a gradient fade between colors in place instead of sliding. Each end is a registered color property with its own keyframe, half a cycle apart, so the blend keeps changing.

Also known as: animate gradient colors css, gradient color transition, @property gradient 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.
