Compatibility task pane

The Compatibility task pane can check one or more pages and CSS files, or all pages and CSS files in a website, for code errors and code that's incompatible with the doctype and CSS schema you specify. You can use the results in the task pane 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 Generate a compatibility report.

When you generate a report, the Compatibility task pane 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 task pane or when you point at the source of the problem in Code view.

  • To open the Compatibility Checker dialog box, click the Run Compatibility Checker button Cc295334.02a658ec-915c-4f10-a127-a1d6fd206ae3(en-us,Expression.10).gif.

  • Click the Generate HTML Report button Cc295334.1137c320-c33b-4e30-b32a-aa75f3ce3d28(en-us,Expression.10).bmp to produce a web page that displays the compatibility results. You can print the web page or display it in a browser and then use the list to check off each issue that you resolve.

  • To sort the list of results, click the name of the column you want to sort by. To reverse a sorted list, click the name of the column again. To restrict the results to those that fit the criteria you select, click the down arrow Cc295334.eb5fc42b-8e20-4d8e-964c-c92f43113355(en-us,Expression.10).gif that appears in the heading of a column and select a criterion to filter the results.


    When the results of the report are filtered, the down arrow Cc295334.eb5fc42b-8e20-4d8e-964c-c92f43113355(en-us,Expression.10).gif of the filtering column appears blue Cc295334.bbc3bb78-660d-44d9-adf6-352e5dadb2ee(en-us,Expression.10).gif instead of black.
