Iridescent Text Effect
An oil-slick sheen where every color shifts in place, without the gradient ever moving. It is one static gradient under a hue-rotate filter that turns a full circle.
Also known as: oil slick text, hue rotate text animation, color shifting text css.

}Customizing this snippet
- Color: set
--txt-coloron the element or a parent. Currently previewing#3b82f6. - Font size: set
--txt-size. Every other dimension is inem, so the whole thing scales together. Currently previewing40px. - Speed: change the duration on the
transitionoranimationshorthand. 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.
