Also known as: folder animation, file upload animation, hairline isometric.

Customizing this snippet

Color: set --hln-color on the element or a parent. Currently previewing #3b82f6.
Base size: set --hln-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
Speed: change the duration on the transition or animation shorthand. 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.
