Dot Grid Card Hover
A faint dot grid in the card's corner spreads across it and starts drifting diagonally on hover. The dots are one radial-gradient tile and the drift moves exactly one tile, so the loop is invisible.
Also known as: dot pattern background css, grid pattern card hover, animated background pattern.

}Customizing this snippet
- Color: set
--hfx-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--hfx-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.
