Accessibility Overview – Lightning Design System

AccessibilityAccessibility Overview

The Lightning Design System provides accessible markup which will serve as a foundation for your application development. In order to make sure you build accessible components, however, you will need to follow the accessibility guidance for our interactive components.

This means that pages are Perceivable, Operable, Understandable and Robust. This includes providing keyboard interaction alternatives for all mouse-based actions, properly identifying all form fields and buttons, providing text based alternatives for all images, videos, icons and SVGs, as well as building components that properly convey their identity, operation model, and state to assistive technologies.

The Design System enables accessible development by providing a set of semantically correct components, each with appropriate ARIA markup so they can be identified correctly to users of assistive technologies.

Standards Compliant Markup

The semantic markup and use of ARIA roles in our components are based on W3C standards and industry best practices. This markup is the perfect starting point for building accessible components.
