Thanks for your replies.
I found and used the 'wonderwebware' to create the menu, but once a put it in my site it throws up validation errors. But, i think i can compare it to the CSS on the 'threestyles tutorials' and see what i can change.
Have you got any ideas, it just keeps telling me 'the property value is marked invalid because it is not supported by the current schema', yet when i change the code in question it just goes bananas. I have not got the relevent experience, me thinks!
