IDs Used in ARIA and Labels Must Be Unique


Under the Accessibility Final Checks, I receive the Problem:

IDs used in ARIA and labels must be unique


  • Omni CMS


Omni CMS Final Checks evaluate all code on a page and detect accessibility issues not meeting WCAG 2.0 (Level AA) standards

It detected the page has HTML code with duplicate IDs. The ID attribute uniquely identifies elements on a page. It does not make sense to duplicate an ID. Duplicate ID's can break the acessibility of labels for forms, table header cells, etc., by the second instance being skipped by screen readers.

This is often caused when copying and pasting content from existing live webpages into the WYSIWYG. Hidden HTML code can be included when pasting rich content into the editor.


Please contact the ITS Service Desk or submit a service request to have this issue repaired.
