Checking a Site for Browser Compatibility
The Browser Compatibility Check feature reviews the code in Web site fi les and iden-
tifi es combinations of HTML and CSS that might have rendering problems in certain
browsers or are unsupported by the browsers. After you run a Browser Compatibility
Check on a page, any potential CSS rendering issues or unsupported CSS code are listed
in the Browser Compatibility panel. A confi dence rating indicates the likelihood of the
bug's occurrence (ranging from a quarter-fi lled circle for a possible occurrence to a fi lled
circle for a very likely occurrence). For each potential issue, the panel displays a link to
documentation about the bug on Adobe CSS Advisor, which is a Web site that details
commonly known browser rendering bugs, and offers solutions for fi xing them.
By default, the Browser Compatibility Check feature checks against Firefox 1.5;
Internet Explorer (Windows) 6.0 and 7.0; Internet Explorer (Macintosh) 5.2; Netscape
Navigator 8.0; Opera 8.0 and 9.0; and Safari 2.0. You can choose which of these brows-
ers to check compatibility with and the minimum browser version you plan to support.
Three levels of potential browser-support problems can arise:

• An error indicates CSS code that might cause a serious visible problem in a particular
browser, such as causing parts of a page to disappear.
• A warning indicates a piece of CSS code that isn't supported in a particular browser,
but that won't cause any serious display problems.
• An informational message indicates code that isn't supported in a particular browser,
but that has no visible effect.

Browser compatibility checks do not change the page in any way.
