Admittedly, Adobe Illustrator is often most certainly not the first choice that comes to mind when it comes to Web design. Fireworks and Photoshop are used much more often, and there are some good reasons for that. Still, although Illustrator has traditionally been used for drawing illustrations and logos, you can use it to design layouts and user interfaces, too.

In fact, in my opinion, you can utilize Illustrator to solve some regular design tasksbetter and more easily than you would do with other tools. With the techniques and tips I’d like to present in this article, I am certain that you will be able to build modular, flexible websites in less time and with less work.
