Slide In Blurred
Shoots in from the left as a squashed, stretched, blurred streak and snaps into a sharp box. Scale fakes the motion blur, and the origin on the right edge keeps it leading.
Also known as: slide in blurred left css, motion blur slide in, whoosh in animation.

}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.
