WAVE evaluates web content against accessibility guidelines like WCAG (Web Content Accessibility Guidelines) and provides clear feedback on how to improve accessibility, making it a crucial tool for ensuring an inclusive web experience.

Features

• Visual feedback: WAVE highlights accessibility issues directly on your webpage, overlaying icons and indicators on the page content to visually represent errors, warnings, and accessibility features.

• WCAG compliance checks: The tool checks your web pages against WCAG 2.1 guidelines, identifying both critical issues and potential areas for improvement to help you ensure compliance with global accessibility standards.

• Contrast checker: WAVE analyzes color contrast on your page to ensure that text is readable for users with visual impairments, helping you meet WCAG requirements for color contrast.

• ARIA evaluation: The tool assesses ARIA (Accessible Rich Internet Applications) attributes to ensure they are used correctly, providing guidance on making dynamic content accessible to screen readers and other assistive technologies.

• Error categorization: WAVE categorizes issues as errors, alerts, features, structural elements, or contrast issues, making it easier to prioritize which problems to address first.

• Browser extension: WAVE is available as a browser extension (for Chrome and Firefox), allowing users to quickly evaluate accessibility directly in their browser without needing to upload content or provide URLs.

• Code view: The tool provides a view of your page’s code with annotations pointing out where accessibility issues occur, making it easier for developers to locate and fix problems at the code level.

• Accessibility features identification: In addition to highlighting errors, WAVE also identifies existing accessibility features (like alt text or ARIA labels), giving you a clear overview of what’s working well on your page.
