The site is geared to users of Cascading Style Sheets (CSS) and features best practices for Web page development.

"With CSS Advisor, the problem that we set out to solve is that people are wasting a huge amount of time trying to make their pages look the same across different browsers," said Kenneth Berger, Adobe product manager for the company's Dreamweaver technology.

CSS Advisor provides a central resource to show developers what they might run into, such as dealing with content overflow on an Internet Explorer page that was not a problem with Firefox, Berger said. Developers can access lists of issues focusing on margins, he said. About 30 browser issues are featured now.

CSS itself has introduced a lot of compatibility issues, Berger said. "There's a major change in Web design, with people changing from table-based layout to CSS layout," said Berger. But CSS offers advantages such as making pages more lightweight so they download faster. CSS pages also are more searchable and more easily accessible by disabled persons.

Adobe has seeded CSS Advisor with a lot of information but the community-driven site allows for user input as well by anyone with an Adobe account. Adobe is administering the site to prevent inaccurate information from being posted.
