Why ::before pseudo-element not working with :visited pseudo-class?

Question

I\'m trying to style my element with pseudo-class and pseudo-element. like hover::before is working perfectly but :visited::before is not working.

Answer 1

Mozilla Developer Network :visited says

Note: For privacy reasons, browsers strictly limit the styles you can apply using an element selected by this pseudo-class: only color, background-color, border-color, border-bottom-color, border-left-color, border-right-color, border-top-color, outline-color, column-rule-color, fill and stroke.

Idea 1: create child element and write CSS for it

*, *:before, *:after {
    box-sizing: border-box;
}
body {
    background-color: #eee;
    font-size: 23px;
    padding: 50px;
    font-family: 'Ubuntu Condensed', sans-serif;
}
.style-3 {
    margin: 20px;
    float: left;
    padding: 20px 20px 20px 20px;
    border: 1px solid #ccc;
    background-color: #fff;
    position: relative;
    text-decoration: none;
}
.style-3 {
    color: green;
}
.style-3:visited {
    color: red;
}
.style-3 span{
    color: #fff;
    margin-left: 20px;
}
.style-3:visited span{
    color: #ccc;
    margin-left: 20px;
}

Idea 2: create a transparent background image with text matching the background color, and change the background color for :visited (not recommended)
