Add/remove some text to div after radiobox is checked/unchecked

I have several radio and checkboxes for displaying some divs. I need to display separate div which show text(e.g. name of author) after clicking on radiobox and also add some text to previous text after clicking on checkboxes. Is it possible to create something like this with the help of css/javascript ? Any advice ? I think that I need to add/remove classes with "content:"bla bla"" in css.
