What is Web Accessibility?
Web accessibility is a design and development approach that makes digital content and services accessible to everyone, including people with disabilities.
Definition
Web accessibility means that websites, applications, and digital technologies are designed so that everyone can:
- Use them
- Understand them
- Navigate them
- Interact with them
- Contribute to their content
Types of Disabilities Addressed
Web accessibility takes into account different types of disabilities:
- Visual: blindness, low vision, color blindness
- Auditory: deafness, hearing impairment
- Motor: mobility difficulties, paralysis
- Cognitive: dyslexia, attention deficit disorders, memory disorders
- Neurological: epilepsy, autism spectrum disorders
Core Principles
Accessibility is based on four fundamental principles (POUR):
- Perceivable: information must be presented in ways all users can perceive
- Operable: interface must be usable by everyone
- Understandable: information must be comprehensible to all
- Robust: content must be compatible with current and future technologies
