Re: any web designers here?
Do you know CSS? If don't than I'll recommend to do it. Its very easy and lots of help available online.
You can change whole style of the page, but changing the CSS that you are using it for that page. You can do it through Javascript or if server side than use PHP or whatever programming language you are using.
But do experiment with it a bit and if you need help with code than come back here. Happy coding :)
