To achieve ADA compliance, websites must adhere to specific guidelines outlined in the Web Content Accessibility Guidelines (WCAG). These guidelines focus on four main principles: perceivability, operability, understandability, and robustness.
Perceivability
Information and user interface components must be presentable to users in ways they can perceive. This includes providing text alternatives for non-text content, ensuring sufficient contrast between text and background, and offering audio and video alternatives for multimedia content.
Operability
User interface components and navigation must be operable, meaning users can interact with the website using various input methods. This involves designing keyboard-navigable interfaces, providing sufficient time for users to complete tasks, and avoiding content that causes seizures.
Understandability
Information and the operation of the user interface must be understandable. This involves using clear and concise language, providing instructions for form completion, and ensuring consistent navigation and identification of elements.
Robustness
Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies. This involves adhering to coding standards and ensuring compatibility with different devices and platforms.
