Reports & Resources WCAG Guidelines Mapped to UDOIT Issues

The following table shows all WCAG guidelines paired with UDOIT issues that check for all or some of that guideline. Due to the nature of human-generated content, UDOIT may not accurately detect issues related to a given guideline, and may report more “false positive” issues just in case.
