Web accessibility refers to the inclusive practice of ensuring that websites and web applications are usable by everyone, including people with disabilities. This involves designing and developing digital content in a way that allows people with disabilities to perceive, understand, navigate, and interact with the web effectively.
Common disabilities that web accessibility aims to accommodate include:
Visual impairments: People who are blind or have low vision may use screen readers, braille displays, or screen magnification software to access web content.
Hearing impairments: Individuals who are deaf or hard of hearing may require transcripts or captions for audio content.
Motor impairments: People with mobility issues may use alternative input devices, such as mouth sticks or eye gaze systems, to navigate websites.
Cognitive impairments: Individuals with cognitive disabilities may benefit from clear navigation, simple language, and consistent layouts to facilitate understanding.

By making websites and web applications accessible, developers and designers can provide equal access to information and services, promoting inclusivity and diversity on the web.
