This check fails when the document has 21 or more pages, but doesn't have bookmarks that parallel the document structure. To add bookmarks to the document, select Bookmarks on the Accessibility Checker panel, and choose Fix from the Options menu. In the Structure Elements dialog box, select the elements that you want to use as bookmarks, and click OK.
You can also access the Structure Elements dialog box by clicking the Options menu on the Bookmark tab and selecting the New Bookmarks From Structure command. See the related WCAG sections: 2. When this check fails, it's possible that the document contains content that isn't accessible to people who are color-blind.
To fix this issue, make sure that the document's content adheres to the guidelines outlined in WCAG section 1. Or, include a recommendation that the PDF viewer use high-contrast colors:. Choose the color combination that you want from the drop-down list, and then click OK. This check reports whether all content in the document is tagged. Make sure that all content in the document is either included in the Tags tree, or marked as an artifact. See the related WCAG sections: 1.
This rule checks whether all annotations are tagged. Make sure that annotations such as comments and editorial marks such as insert and highlight are either included in the Tags tree or marked as artifacts. To have Acrobat assign tags automatically to annotations as they're created, choose Tag Annotations from the Options menu on the Tags panel. Because tabs are often used to navigate a PDF, it's necessary that the tab order parallels the document structure.
To fix the tab order automatically, select Tab Order on the Accessibility Checker panel, and choose Fix from the Options menu. Click the Page Thumbnails panel on the navigation pane. Click a page thumbnail, and then choose Page Properties from the Options menu. In the Page Properties dialog box, choose Tab Order.

Select the content, and then apply tags as necessary. Assign tags using the Tags panel. Elements that make the screen flicker, such as animations and scripts, can cause seizures in individuals who have photosensitive epilepsy. These elements can also be difficult to see when the screen is magnified. If the Screen Flicker rule fails, manually remove or modify the script or content that causes screen flicker. See these related WCAG sections: 1.
Level A. Content cannot be script-dependent unless both content and functionality are accessible to assistive technologies. Make sure that scripting doesn't interfere with keyboard navigation or prevent the use of any input device. Check the scripts manually. Remove or modify any script or content that compromises accessibility. Level A , 4. This rule check applies to documents that contain forms with JavaScript. If the rule check fails, make sure that the page does not require timed responses.
Edit or remove scripts that impose timely user response so that users have enough time to read and use the content. The best way to create accessible links is with the Create Link command, which adds all three links that screen readers require to recognize a link.
Make sure that navigation links are not repetitive and that there is a way for users to skip over repetitive links. If this rule check fails, check navigation links manually and verify that the content does not have too many identical links.
Also, provide a way for users to skip over items that appear multiple times. For example, if the same links appear on each page of the document, also include a "Skip navigation" link.
In an accessible PDF, all form fields are tagged and are a part of the document structure. In addition, you can use the tool tip form filed property to provide the user with information or to provide instructions.
Level A , 3. Screen readers don't read the alternate text for nested elements. Therefore, don't apply alternate text to nested elements. Make sure that alternate text is always an alternate representation for content on the page. If an element has alternate text, but does not contain any page content, there is no way to determine which page it is on. If the Screen Reader Option in the Reading preferences is not set to read the entire document, then screen readers never read the alternate text.
Alternate text can't hide an annotation. If an annotation is nested under a parent element with alternate text, then screen readers don't see it.
This report checks for content, other than figures, that requires alternate text such as multimedia, annotation, or 3D model. If an element has alternate text but does not contain any page content, there is no way to determine which page it is on. If the Screen Reader Options in the Reading preferences is not set to read the entire document, then screen readers don't read the alternate text. Because table structure can be complex, it is best practice to check them for accessibility manually.
