This tool helps identify accessibility issues in web content by analyzing HTML code against WCAG (Web Content Accessibility Guidelines) standards. It provides feedback about potential barriers that might prevent people with disabilities from using your website effectively.
Check out the live demo: Web Accessibility Checker
- Content creators
- Web editors
- Quality assurance testers
- Anyone who needs to check web content for accessibility compliance
- Copy your HTML code
- Paste it into the textarea
- Click "Check Accessibility"
- Review the results
The checker shows four categories:
- Violations: Critical issues that must be fixed
- Needs Review: Issues that require human judgment
- Passed: Elements that meet accessibility standards
- Not Applicable: Rules that don't apply to your content
### Select Element Accessibility Test
#### Failing Example (Shows Violation):
```html
<!DOCTYPE html>
<html>
<head>
<title>Product Form</title>
</head>
<body>
<main>
<h1>Product Details</h1>
<form>
<div>
<select>
<option value="">Select category</option>
<option value="1">Electronics</option>
<option value="2">Books</option>
</select>
</div>
</form>
</main>
</body>
</html>Why it fails:
- The
<select>element has no associated label - Screen readers can't properly announce the purpose of this control
- Users have no context about what they're selecting
<!DOCTYPE html>
<html>
<head>
<title>Product Form</title>
</head>
<body>
<main>
<h1>Product Details</h1>
<form>
<div>
<label for="category">Category:</label>
<select id="category" name="category">
<option value="">Select category</option>
<option value="1">Electronics</option>
<option value="2">Books</option>
</select>
</div>
</form>
</main>
</body>
</html>How it's fixed:
- Added a
<label>element with a properforattribute - Added matching
idattribute to the select element - Added
nameattribute for form submission - Screen readers can now properly announce "Category" when focusing the select element
To test:
- Copy either example into the accessibility checker
- The first example will show the "select-name" violation
- The second example will pass the check
