How do you check if a checkbox is checked in CSS?

A checkbox cannot be checked in CSS, unfortunately. It relies on the checked attribute of the input element, and attributes cannot be modified via CSS. Alternatively, you could look into a JavaScript solution, but of course the best way would be to edit the HTML directly.

How do you style a checkbox when checked?

It is possible to style a checkbox using Pseudo Elements like :before, :after, hover and :checked. To style the checkbox the user first needs to hide the default checkbox which can be done by setting the value of the visibility property to hidden.
