Frosted glass
A translucent pane over slowly moving color.
Glassmorphism Card
The classic glassmorphism card: a frosted pane over two gradient orbs that slowly circle behind it, so you watch the blur at work. Semi-transparent fill, backdrop-filter, rim light.
Also known as: glass card css, glassmorphism card html css, frosted glass card.

</div>Customizing this snippet
- Color: set
--gls-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--gls-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - 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.
