What you describe can only be achieved with javascript Š
However, you can "show/hide" text (and in some browsers images) using hover as shown here: http://www.meyerweb.com/eric/css/edge/popups/demo.html and here: http://www.meyerweb.com/eric/css/edge/popups/demo2.html
This isn't what you asked for, but it might be helpful depending on what you're really trying to achieve.
