Bookmark Save Checkbox
A bookmark ribbon that fills from the top and dips like it just dropped onto the page, while the word Save rolls up to Saved. The fill is a clipped copy of the icon, so it pours in cleanly both ways.
Also known as: bookmark checkbox css, save for later toggle, bookmark icon animation css.

}Customizing this snippet
- Color: set
--chk-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--chk-size. Every other dimension is inem, so the whole thing scales together. Currently previewing24px. - 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.
