I've been working on a code that customizes the appearance of the checkbox "tick" mark when it's selected:
.x-input-checkbox:checked + .x-field-mask:after {
//Customize your styles here
}
Just to clarify, this snippet only affects the check mark itself, not the entire checkbox field.
However, I'm struggling to figure out how to change the background color of the whole checkbox field upon selection using CSS alone. Any ideas?
