Thats Mr. Danforths Webpage by the way. Look at his buttons on his navigation bar, see how they chnage color when your mouse goes over it. How do you do that?

Thanks in advance

Again i dont know the actual raw HTML code but if you have Dreamweaver then it will make it a hell of a lot easier. I am pretty sure if you jsut search for a rollover code in any search engine you will get results.
sweet.

CRAP I DONT HAVE DREAMWEAVER! What is it? Ive been hearing alot about it lately for some reason. I have Adobe Photoshop 6.0. Can you give me the link to the Dreamweaver site?

Thanks

The link to the dreamweave web site is here

It's a great program though expensive if you actually purchase it. What I'm saying (NO I'm not promoting warez) is that you can use it for 30 days as a trial but after that time they ask you to remove the software or to purchase it.

It's a real nice piece of equipment though.

So Check it out!!
