The Accessibility panel lives directly inside the Divi Visual Builder. It detects whether you are on Divi 4 or Divi 5 and loads the matching panel automatically, so the workflow is the same in both.
Open the panel
With a page open in the Divi Builder, open the Accessibility trigger from the builder controls. If the trigger is not visible, a floating button appears as a fallback. Both open the same panel.
Run a scan and read severities
Click Run Scan. The panel returns two lists: Violations (confirmed issues) and Needs Manual Review (items the engine cannot decide automatically). Everything is grouped by rule and tagged Critical, Serious, Moderate, or Minor.
See the detail behind an issue
Expand any issue to see the failing selector, plain-English fix guidance, and, for contrast issues, a card with the color swatches, the exact ratio, and AA and AAA pass or fail badges.
Jump to the element
Click Highlight on any issue and the offending element is outlined and scrolled into view on the canvas, so you can see exactly what the scanner is pointing at.
Turn on Watch mode in Settings to have the panel re-scan automatically as you edit, so the list stays current while you work.
