Drops a short way from above while scaling up from 96 percent, anchored at its top edge. The motion menus and dropdowns use, kept quick at half a second.
Also known as: css fade in from top, fade down animation css, dropdown fade in.

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