Weekday Picker Checkboxes
Seven round day chips for a repeat schedule. Checked days pop into the accent, and neighbors that are both checked join into one pill through a bridge drawn with :has() and the + combinator.
Also known as: day of week picker css, weekday selector checkbox, repeat days picker.

}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.
