Aurora Text Effect
Teal, green and violet bands drift through the letters while a pink veil drifts the other way, like the northern lights. Each layer is an em-sized tile that loops by exactly one tile.
Also known as: aurora gradient text, northern lights text css, animated aurora text.

}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.
