Using Hover Effects with pseudo class :active or on click

Hi, how couId I apply hover effects when it's clicked some div has some class hover.css, I tried copy the css rules and added the pseudo class :active but it didn't work, Thanks

The issue contains a question about applying Hover's CSS effects when an element is clicked, but it names no file, test, or entry point. First clarify whether the project needs usage documentation or an example, then define the expected behavior for the :active or click interaction before considering the issue complete.
