You can not use adobe illustrator to make HTML websites. What you can do and that is the way i do it, make a template with the size for example 1024x768 RGB and make your layout without the text in it.
You then copy and paste everything in photoshop cut the pieces out you need and save them. When finished you can then import them in macromedia dreamweaver. (look at my website http://www.roos-design.nl),
another way is to use macromedia flash you can import complete illustrator artwork in there and the fun part is that it stays vector oriantated.
I hope this works for you!
