Ensuring your website is accessible to all users is not just a best practice—it's a necessity. The Web Content Accessibility Guidelines (WCAG) 2.1 and 2.2 Level AA provide a framework to make web content more accessible to people with disabilities. This checklist is designed to guide you through the essential criteria to achieve WCAG 2.1 and 2.2 Level AA compliance.
Understanding WCAG 2.2 AA
WCAG 2.2 builds upon previous versions by adding new success criteria to address the evolving needs of users, particularly those with cognitive and learning disabilities, low vision, and users on mobile devices. Achieving Level AA compliance ensures a broader range of accessibility without the complexity of Level AAA.
The Four Principles of Accessibility
WCAG is organized around four core principles:
Perceivable: Information and user interface components must be presentable to users in ways they can perceive.
Operable: User interface components and navigation must be operable.
Understandable: Information and the operation of the user interface must be understandable.
Robust: Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies.
WCAG 2.1 and 2.2 AA Checklist
Perceivable
Text Alternatives: Provide text alternatives for non-text content (e.g., images, videos).
Time-based Media: Offer alternatives for time-based media, such as transcripts for audio and captions for videos.
Adaptable: Create content that can be presented in different ways without losing information or structure.
Distinguishable: Make it easier for users to see and hear content, including separating foreground from background.
Operable
Keyboard Accessible: Ensure all functionality is available from a keyboard.
Enough Time: Provide users enough time to read and use content.
Seizures and Physical Reactions: Do not design content in a way that is known to cause seizures or physical reactions.
Navigable: Provide ways to help users navigate, find content, and determine where they are.
Understandable
Readable: Make text content readable and understandable.
Predictable: Make Web pages appear and operate in predictable ways.
Input Assistance: Help users avoid and correct mistakes.
Robust
Compatible: Maximize compatibility with current and future user agents, including assistive technologies.
Implementing the Checklist
To effectively implement this checklist:
Audit Your Website: Conduct a thorough audit to identify areas that do not meet WCAG 2.1 and 2.2 Level AA standards.
Prioritize Issues: Address issues that have the most significant impact on accessibility first.
Engage Experts: Work with accessibility experts to ensure compliance and to train your team.
Test with Users: Involve users with disabilities in testing to gain valuable feedback.
