Supporting Accessibility

When customizing components, be careful in preserving code that ensures accessibility, such as the aria attributes.

Accessible software and assistive technology enable users with disabilities to use and interact with the products you build. Aura components are created according to W3C specifications so that they work with common assistive technologies. While we always recommend that you follow the WCAG Guidelines for accessibility when developing with the Lightning Component framework, this guide explains the accessibility features that you can leverage when using components in the ui namespace.
