Web accessibility refers to the practice of making websites, web applications, and other digital content accessible to people with disabilities. This includes individuals who are blind or have low vision, deaf or hard of hearing, have mobility impairments, or have cognitive or learning disabilities.
Web accessibility is important because it allows people with disabilities to access and use the same information and services as everyone else. It also helps to ensure that people with disabilities have equal opportunities to participate in the digital economy and society.
To make a website or web application accessible, developers need to follow certain guidelines and best practices. This includes using semantic HTML tags to structure the content, providing alternative text for images, using colours and fonts that are legible and have sufficient contrast, and making sure that all interactive elements are keyboard-navigable. Developers also need to test their websites and web applications to ensure that they are fully accessible to people with disabilities.
Overall, web accessibility is a crucial aspect of the design and development of digital content and is essential for ensuring that everyone can access and use the internet.
