Toggle Button Group
A text-formatting toolbar of pressable toggles: bold, italic, underline and strike. Each key sinks when pressed, pops into its filled on state and combines with the others. Four hidden checkboxes.
Also known as: css toggle button, button group css, aria pressed button.

Customizing this snippet
- Color: set
--btn-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--btn-size. Every other dimension is inem, so the whole thing scales together. Currently previewing18px. - 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.
