WCAG, or Web Content Accessibility Guidelines, are a set of internationally recognized standards for making web content more accessible to people with disabilities. Developed by the World Wide Web Consortium (W3C), WCAG provides a framework for creating accessible websites, applications, and other digital content. The guidelines are organized into four main principles: perceivable, operable, understandable, and robust.

The perceivable principle ensures that users can perceive the information presented, meaning it must be available to their senses. This includes providing text alternatives for non-text content, such as images, and making sure content can be presented in different ways without losing meaning. The operable principle focuses on making user interface components and navigation easy to use. This involves ensuring all functionality is available via a keyboard, giving users enough time to read and use content, and designing interfaces that do not cause seizures.

The understandable principle aims to make content easy to understand. This means text should be readable and understandable, content should appear and operate in predictable ways, and users should be helped to avoid and correct mistakes. Finally, the robust principle ensures that content can be interpreted reliably by a wide variety of user agents, including assistive technologies. This means content should be compatible with current and future user agents.

WCAG standards are typically categorized into three conformance levels: A, AA, and AAA. Level A is the lowest and requires sites to meet a minimum level of accessibility. Level AA is the most commonly targeted level, representing a good balance between accessibility and implementation effort. Level AAA is the highest level, requiring the most stringent accessibility, which can sometimes be challenging to achieve fully. Adhering to WCAG standards helps ensure that digital content is usable by the broadest possible audience.
