Puff In
Starts oversized, blurred and transparent, then collapses into focus on an ease-in curve so it lands with a small thump. Animates filter, so keep it for a few elements.
Also known as: puff in center css, puff in animation, blur zoom in css.

}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.
