I have a pattern that I would like to have appear in my site on the side containers (not sure if that's the right wording). I don't want just a plain color to surround the content, I'd like to create a pattern in Illustrator and have this replace a solid color. Is this possible?
Thanks for any help!
Yes it's a very common technique
You make a tile that will repeat and set it as a background image using CSS.
To have a test run you could easily find a background image on the web for free and have a go with that. I Have a feeling that Nancy_O has a few on her site.
Here's a link to Nancy_O's freebies http://alt-web.com/Backgrounds.shtml
