On the Validate -> Accessibility tab, you can perform accessibility validation of the page currently selected in the content tree, specifically of its version displayed in the currently selected view mode (Preview or Live site). Please note that even if you navigate to some other page in the preview or live site mode using links on displayed pages and switch to the Validate tab, actions performed on this tab will still be related to the page selected in the content tree.







Your data is sent to an external 3rd party validation service. If you have sensitive, non‑public content, we recommend that you use some other way to validate your website.



You can perform the validation against several standards:


BITV 1.0 (Level 2)

U.S. Section 508

Stanca Act

WCAG 1.0 (Level A)

WCAG 1.0 (Level AA)

WCAG 1.0 (Level AAA)

WCAG 2.0 (Level A)

WCAG 2.0 (Level AA)

WCAG 2.0 (Level AAA)


You can choose the standard using the Standard drop-down list.




Make sure to use the HTML validator, CSS validator and Link checker before you use the accessibility validator to ensure valid markup.


The following actions are available in the top row:


Approve Validate - performs accessibility validation on the page currently selected in the content tree and displays validation results below.

Macro_tree View source - opens a new pop-up window displaying the source code of the page selected in the content tree.


The following actions are only available after performing validation which showed that the document contains accessibility issues:


WindowNewValidators Show results in new window - displays validation results in a new window.

Export to various formats - after clicking the OtherActions icon in the first column of the results grid, a context menu is displayed, offering options for export of listed data to various types of files.


If the document contains accessibility issues, a grid is displayed in the main area, listing all issues detected by the validation. You can see the following information about each issue:


Line - line of the HTML code on which the issue appears.

Column - column of the HTML code (i.e. number of characters from the beginning of the respective line) where the issue appears.

Accessibility rule - the standard's accessibility rule based on which the error was generated.

Error - message describing the validity issue.

Fix suggestion - description of steps to be taken to address the accessibility issue.
