Google Chrome's Lighthouse accessibilty audit checks your page and gives it an accessibility score out of 100.
A score of 100 indicates that a page fulfills the criteria Lighthouse can programatically test. It does not indicate that your page is compliant to a particular level.
It also provides lists of:
- Suggested improvements based on failed tests
- Additional manual tests to perform
- Passed tests
- Tests that aren't applicable based on the content of the page
This is a useful tool to obtain a quick overview of ways to enhance the experience for users of assistive technologies.
