Web accessibility means that people with disabilities can perceive, understand, navigate, and interact with the web. It is important to ensure equal access and opportunity for all users, including those with visual, auditory, physical, speech, cognitive or neurological disabilities. Key principles of accessible design include providing alternative text for images, using headings for tables, ensuring all forms can be completed and submitted, making links meaningful without surrounding context, captioning media, and allowing users to skip repetitive content. Accessibility should be considered from the beginning of web development and evaluated throughout using tools as well as human review.
