Big Checkbox
A large checkbox with a bold tick and a padded label, so the whole row is an easy tap target. Checking gives the box a springy pop while the tick draws. Raise --chk-size to grow it further.
Also known as: how to make a checkbox bigger css, large checkbox css, css enlarge checkbox.

}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.
