How Can I Modify CSS ':after' Selectors Using jQuery?

Utilizing jQuery to Modify ":after" Selectors

Accessing the ":after" CSS selector using jQuery can present certain challenges, as the ":after" element exists outside the DOM and is not directly accessible. However, there are workarounds to achieve the desired modification.

Custom CSS class:

One approach is to create a new class with a customized ":after" element that takes precedence over the original. For instance:

.pageMenu .active.changed:after {
    border-top-width: 22px;
    border-left-width: 22px;
    border-right-width: 22px;
}

jQuery manipulation:

Next, use jQuery to toggle the custom class on the target element:

$('.pageMenu .active').toggleClass('changed');

Pseudo-element manipulation:

Alternatively, explore "Manipulating CSS pseudo-elements using jQuery (e.g. :before and :after)" for additional techniques to read or override pseudo-elements.
