Perceivable

Perceivable content ensures that all users can perceive the information presented. This includes providing text alternatives for non-text content, captions for multimedia, and ensuring content can be presented in different ways without losing meaning.

Example:

Operable

Operable design ensures that users can navigate, find content, and interact with the interface. This includes providing keyboard access to all functionality, allowing sufficient time for users to read and use content, and avoiding content that causes seizures.

Example:

Understandable

Understandable content ensures that information and the operation of the user interface are understandable. This includes making text content readable and understandable, providing clear and consistent navigation, and helping users avoid and correct mistakes.

Example:

Robust

Robust content ensures that it can be interpreted reliably by a wide variety of user agents, including assistive technologies. This includes adhering to web standards and ensuring compatibility with current and future user agents.

Example:

Keyboard Accessibility

Keyboard accessibility ensures that all functionality can be operated using a keyboard. This includes providing keyboard shortcuts, ensuring focus order is logical, and avoiding keyboard traps.

Example:

Screen Reader Compatibility

Screen reader compatibility ensures that content is accessible to users who rely on screen readers. This includes using semantic HTML, providing descriptive text alternatives, and ensuring landmarks are used for navigation.
