Supporting Accessibility

When customizing components, be careful to preserve 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. We recommend that you follow the WCAG Guidelines for accessibility when developing with the Lightning Component framework.

• Accessibility for Lightning Base Components

  This section explains the accessibility features on components in the lightning namespace.

• Write Aura Component Accessibility Tests

  When you develop with Aura components, you can use Salesforce’s test tools to check for common accessibility issues.
