Compatibility panel

The Compatibility panel can check one or more pages and CSS files, or all pages and CSS files in a site, for code errors and code that's incompatible with the doctype and CSS schema you specify. You can use the results in the panel to view information about each issue and to go to the line of code that contains the issue. You can also copy one or more of the results or generate a web page of the entire report. For more information, see Compatibility reports.

When you generate a report, the Compatibility panel contains the following columns:

  • Status   Shows an icon that represents the type of file that contains the issue and the status of the file.

  • ****Page   ****Lists the web page that contains an issue and the location of the page.

  • ****Line   ****Lists the number of the line in Code view that contains the issue.

  • ****Issue Type   ****Lists the type of issue, either Incompatibility or Code Error. The results in this column can be driven by the DocType declaration in each page or the schema that you select when you run the report.

  • ****Schema   ****Identifies the document type or level of CSS that the code is incompatible with.

  • ****Problem Summary   ****Describes the code error or the reason the code is incompatible with the schema. The content of this column also appears in a ScreenTip when you point at a row in the panel or when you point at the source of the problem in Code view.
