Yes! All content created for the Aurora design system follows WCAG 2.1 requirements for accessibility. The Aurora design system also draws some components from the Web Experience Toolkit (WET) which has undergone extensive accessibility testing.
Where applicable, documentation refers to tips, tricks and best practices for ensuring accessibility for each component. A future version of Aurora will include more basic principles and guidelines for ensuring accessibility across your website or application.
Components in the design system were also reviewed from consultants from the WET 4 team, with a focus on reviewing accessibility. The Aurora website was also reviewed and tested against WCAG 2.1 standards.
