Accessibility in web design refers to the practice of creating websites and web applications that are usable and accessible to people with diverse abilities, including those with visual, auditory, motor, or cognitive impairments. Key aspects of accessibility in web design include:

• Providing alternative text (alt text) for images and other non-text content
• Ensuring proper color contrast and text readability for users with visual impairments
• Enabling keyboard navigation and providing clear focus indicators for users who cannot use a mouse
• Incorporating screen reader-friendly markup and structure for users with visual impairments
• Optimizing content and interactions for users with motor impairments or cognitive disabilities
• Complying with web accessibility standards and guidelines, such as WCAG (Web Content Accessibility Guidelines)

Accessible web design ensures that all users, regardless of their abilities, can access and interact with the website's content and functionality.
