There is no easy way to convert AI to HTML/CSS Split the design and save these parts as png/jpg images, then you can use them in your template.
background: url(../images/a-small-part.jpg) no-repeat 0 0;
So you're giving me hope !! I was afraid if I have to learn photoshop for web-designing.
Just to be sure, is designing in photoshop mandatory? Or will it be very helpful for me, if I learn photoshop for web-designing??
Thanks for your help ..
Basically Illustrator is not for web design, is for graphic design. I don't know so much about illustrotor, so I can't give you a good advice how to extract images from it and then use them in html.
As other already said, I recomend to learn Photoshop(it is easier than AI) and design websites with it.
If you have a great idea and good design skills, learn CSS3 and you'll be able to design premium websites without Photoshop, Illustrator or any other design software. As an example: My latest template is 90% based on CSS(3), it was designed in Photohop by another designer, but for code I've used only a very small number of graphics.
