Web accessibility is a fundamental principle in the design and development of websites and digital applications. It encompasses the idea that online content should be perceivable, operable, and understandable by people of all abilities, ensuring equal access and usability for everyone. In today’s interconnected world, where the internet plays a central role in various aspects of daily life, from education and employment to social interactions and government services, web accessibility is not just a nice-to-have feature—it is a legal and ethical imperative. Designing for all users’ means considering a wide range of disabilities and impairments, such as visual, auditory, motor, cognitive, and neurological challenges. Visual impairments may include blindness, low vision, or color blindness, while auditory impairments refer to hearing loss or deafness. Motor impairments encompass conditions that affect physical dexterity and coordination, such as paralysis or tremors. Cognitive and neurological impairments can range from attention disorders like ADHD to cognitive disabilities like dyslexia or autism.

The Web Content Accessibility Guidelines WCAG, developed by the World Wide Web Consortium W3C, serves as a global standard for web accessibility. These guidelines are organized into four key principles – perceivable, operable, understandable, and robust POUR. Under the perceivable principle, websites must provide content that can be perceived by all users, regardless of their disabilities. This includes alternative text for images, transcripts for audio and video content, and adaptable text sizes and color contrasts for those with visual impairments. The operable principle focuses on ensuring that web interfaces are easily navigable and usable by various means, such as keyboards, screen readers, and voice commands. Features like keyboard shortcuts, skip navigation links, and consistent navigation menus contribute to operability. The understandable principle emphasizes the need for clear and concise content, avoiding jargon and complex language, and offering input validation and error messages that guide users in completing tasks successfully. Lastly, the robust principle encourages the use of technologies and coding practices that can withstand technological changes and remain accessible over time.
