Web accessibility refers to the practice of making websites and web applications usable by people with disabilities. It encompasses a wide range of disabilities, including visual, auditory, motor, and cognitive impairments. The goal of web accessibility is to ensure that everyone, regardless of their abilities, can access and use a website.
Web accessibility is achieved through a combination of technical and design standards and guidelines, such as the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines (WCAG). These guidelines provide a set of best practices and standards for creating accessible websites, including providing alternative text for images, using descriptive link text, and designing for keyboard navigation.
Web developers and designers use a variety of techniques to make websites accessible, such as using semantic HTML markup, providing alternative text for images, and ensuring that the site is navigable using a keyboard alone. They also need to ensure that the website is compatible with assistive technologies such as screen readers and magnifiers, which are used by people with visual impairments.
Web accessibility is an important aspect of web development, as it ensures that everyone can access the information and services provided by a website. It’s also legally required by many countries and organizations, as it’s considered as a fundamental human right.
