I am currently building a site to aaa conformity and would like to add the option of changing the colour theme of the page ie from black text on white background to yellow text on black background or images displayed to no images displayed. Any ideas on the easiest/neatest way of including this option in my scripts? php, css, javascript.

Found an easy way (well looks easy)
