Can I have an onclick effect in CSS?

Question

I have an image element that I want to change on click.

This works:

#btnLeft:hover {
    width:7         


        

Answer 1

The closest you'll get is :active:

#btnLeft:active {
    width: 70px;
    height: 74px;
}

However this will only apply the style when the mouse button is held down. The only way to apply a style and keep it applied onclick is to use a bit of JavaScript.
