WAVE is available for Firefox and Google Chrome. See the download links below for more information.
About the WAVE Tool
WAVE is a browser plugin that allows Web developers to view possible accessibility errors and tagged structure on individual pages.
Unlike reporting tools like Compliance Sheriff, WAVE allows a tester to see how a page is structured in a holistic fashion instead of identifying issues sequentially.
It is similar to the online WAVE Webpage Accessibility Evaluator, but allows a user to test password protected pages, preview pages or unposted .html files.
Example WAVE Icon Report
For example, in the screen capture below, the WAVE toolbar found a number of issues with an HTML form, including:
- A form with several input fields missing the LABEL tag (indicated with a red no-label icon)
- An empty
<h2>tag (indicated with a blue H2 icon plus a red warning icon).
- The blue table icon also indicates the form is enclosed in a layout table
The WAVE Web site contains a comprehensive list of the accessibility icons, complete with descriptions and explanations of each.
Another important option on WAVE us the ability to disable styles. This allows a tester to see the underlying order of a page and ensure that it is comprehensible on a screen reader or other device without CSS style support.
See the documentation for each WAVE Tool to learn more about the functions of the tool.
