This digest can help answer that question. Nine different tools (Alfa, ASLint, Axe, Equal Access, HTML CodeSniffer, Nu Html Checker, QualWeb, Testaro, and WAVE) tested the page to check its compliance with their accessibility rules. In all, the tools define about 915 rules, which are classified here into about 300 accessibility issues.
