Accessibility
A set of principles, guidelines, and practices that ensure digital products and services can be used by people of all abilities and circumstances.
Accessibility
Accessibility (often abbreviated as a11y) is a fundamental aspect of design ethics that ensures digital experiences are usable by people with diverse abilities, disabilities, and circumstances. It represents the intersection of inclusive design, technical implementation, and human rights in the digital realm.
Core Principles
POUR Guidelines
The Web Content Accessibility Guidelines (WCAG) establish four fundamental principles:
- Perceivable: Information must be presentable in ways all users can perceive
- Operable: Interface components must be operable by all users
- Understandable: Information and operations must be understandable
- Robust: Content must be compatible with current and future tools
