Web accessibility ensures that websites, tools, and technologies are designed and developed so that people with disabilities can use them effectively. This includes people with visual, auditory, physical, speech, cognitive, and neurological disabilities.
Key principles include: perceivable, operable, understandable, and robust content. These guidelines help create inclusive digital experiences for all users.
