Only detect click event on pseudo-element

Question

My code is:

p {
    position: relative;
    background-color: blue;
}

p:before {
    content: \'\';
    position: absolute;
    left:100%;
    width: 10px;
         


        

Answer 1

Actually, it is possible. You can check if the clicked position was outside of the element, since this will only happen if ::before or ::after was clicked.

This example only checks the element to the right but that should work in your case.

span = document.querySelector('span');

span.addEventListener('click', function (e) {
    if (e.offsetX > span.offsetWidth) {
        span.className = 'c2';
    } else {
        span.className = 'c1';
    }
});

div { margin: 20px; }
span:after { content: 'AFTER'; position: absolute; }

span.c1 { background: yellow; }
span.c2:after { background: yellow; }
