Web accessibility means designing websites that everyone can use, including people with visual, auditory, motor, or cognitive disabilities. It's both the right thing to do and, increasingly, a legal requirement.
Who Needs Accessible Websites?
More people than you might think:

- Blind users: Navigate using screen readers that read page content aloud
- Low vision users: Need high contrast, resizable text, screen magnification
- Deaf users: Require captions for audio/video content
- Motor impaired: May not use a mouse, navigate via keyboard or specialized devices
- Cognitive disabilities: Benefit from clear layouts, simple language, consistent navigation
- Temporary disabilities: Broken arm, lost glasses, even bright sunlight
About 1 in 4 adults in the US has some form of disability. That's a significant portion of potential customers.
The Legal Landscape
ADA (Americans with Disabilities Act)
The ADA requires businesses to provide accessible services. Courts have increasingly applied this to websites, especially for businesses with physical locations.
Lawsuits Are Real
Web accessibility lawsuits have increased dramatically. Small businesses, not just large corporations, receive demand letters and face legal action. Settlements typically range from $5,000-$25,000 for small businesses, plus attorney fees and required remediation.
WCAG as the Standard
While the ADA doesn't specify technical standards, courts and regulators typically reference WCAG (Web Content Accessibility Guidelines). WCAG 2.1 Level AA is the common target for compliance.
Core Accessibility Principles (POUR)
Perceivable
Users must be able to perceive the content:
- Images have alt text describing them
- Videos have captions
- Color isn't the only way to convey information
- Text has sufficient contrast against background
Operable
Users must be able to operate the interface:
- All functionality accessible via keyboard
- No time limits or ability to extend them
- No content that flashes more than 3 times per second
- Skip links to bypass repetitive navigation
Understandable
Users must be able to understand content and interface:
- Language of page is identified
- Navigation is consistent
- Error messages are clear and helpful
- Forms have clear labels
Robust
Content must work with current and future technologies:
- Valid HTML code
- Proper use of ARIA labels when needed
- Works with assistive technologies
Common Accessibility Issues
- Missing alt text: Screen readers can't describe images
- Poor color contrast: Text hard to read for low vision users
- Keyboard traps: Can't navigate away from certain elements with keyboard
- Missing form labels: Screen readers don't know what fields are for
- Unlabeled buttons: "Click here" or icon-only buttons with no text alternative
- Auto-playing media: Disorienting for screen reader users
- Missing page structure: No proper heading hierarchy (H1, H2, H3)
Testing Your Website
Automated Testing
- WAVE: Free browser extension that highlights issues
- axe DevTools: Comprehensive automated testing
- Lighthouse: Built into Chrome, includes accessibility audit
These catch about 30-40% of issues. Manual testing is also essential.
Manual Testing
- Keyboard navigation: Tab through your site without a mouse
- Screen reader: Use VoiceOver (Mac) or NVDA (Windows) to hear your site
- Zoom: Increase to 200% and ensure everything still works
- Color contrast checker: Verify text meets contrast requirements
Quick Wins
Start improving accessibility today:
- Add alt text to all images: Describe what's shown, or use empty alt="" for decorative images
- Check color contrast: Use a contrast checker tool
- Label all form fields: Every input needs a visible or screen-reader-accessible label
- Use proper headings: H1 for main title, H2 for sections, etc.
- Add skip links: "Skip to main content" link at top
- Test keyboard navigation: Tab through your whole site
Accessibility Overlays: A Warning
You may have seen "accessibility widgets" that promise instant compliance. These overlays don't work as advertised and may actually make things worse. They've been criticized by accessibility experts and haven't prevented lawsuits. Real accessibility requires building it into your site, not bolting on a widget.
The Business Case
Beyond legal compliance:
- Larger audience: Don't exclude 25% of potential customers
- SEO benefits: Many accessibility practices also improve search rankings
- Better for everyone: Captions help in noisy environments, high contrast helps in bright sunlight
- Brand reputation: Demonstrates values and inclusivity
The Bottom Line
Accessibility isn't optional — it's essential. The legal risks are real, but more importantly, an inaccessible website excludes millions of potential customers.
Start with an audit to understand where you stand, prioritize the biggest issues, and build accessibility into your ongoing web maintenance.
