Glossy Shine Text
A crisp double streak of light flashes diagonally across glossy letters, then rests. Unlike a soft shimmer the text stays full color, and the pause keeps it from feeling busy.
Also known as: diagonal shine text css, text shine animation, glare sweep 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.
