A11y Quick Check
Instantly scan HTML for structural accessibility violations.
What does this tool check?
This tool performs a structural analysis of your HTML to catch the "low hanging fruit" of web accessibility:
- Missing Language Attributes: The
<html>tag must declare alangattribute (e.g.lang="en") so screen readers know which voice profile/pronunciation engine to use. - Missing Alt Text: All
<img>tags must have analtattribute. Even if the image is purely decorative, you must include an empty attributealt=""so screen readers know to skip it. - Empty Links & Buttons: Interactive elements like
<a>and<button>must have discernible text. If you use an icon inside a button without text, you must add anaria-labelto the button. - Form Labels: All inputs (except hidden and submit/button types) must have an associated
<label>or anaria-label.
Note on Automated Testing
Automated tools can only catch about 20-30% of accessibility issues. Passing this test does not guarantee your site is fully accessible or WCAG compliant. You should always perform manual keyboard testing and screen reader testing.
