Web Accessibility: Why Compliance Isn't Optional Anymore

Web accessibility used to be treated as "nice to have." That window has closed. Lawsuits over inaccessible sites have exploded — and beyond the legal angle, accessibility almost always improves UX for everyone, not just users with disabilities.

What accessibility actually means

The Web Content Accessibility Guidelines (WCAG) cover four principles. Your site should be:

• Perceivable — users can see/hear/feel the content (alt text, captions, sufficient contrast).
• Operable — users can navigate without a mouse (keyboard support, no time traps).
• Understandable — content and operation are predictable (clear labels, error messages).
• Robust — works with assistive technologies (screen readers, voice input, switch devices).

The five accessibility wins that solve 70% of issues

1. Alt text on every meaningful image. Decorative images get alt=""; meaningful images describe what they convey.
2. Sufficient colour contrast. 4.5:1 for body text minimum. Use the WebAIM contrast checker.
3. Keyboard navigation. Every interactive element should be reachable and usable with Tab/Enter/Space alone.
4. Form labels. Every input needs a programmatically associated <label>. "Placeholder is a label" is not accessibility.
5. Heading hierarchy. One H1 per page. Don't skip levels. Headings describe sections, not visual style.

How to audit your site in 30 minutes

1. Run the page through axe DevTools (free Chrome extension).
2. Try to navigate with keyboard only — no mouse, no trackpad. Tab through every page.
3. Turn on macOS VoiceOver or Windows Narrator and listen to the page being read.
4. Use Lighthouse's accessibility audit in Chrome DevTools.

You'll find the top issues fast. Fix the highest-impact ones first.

The legal landscape (briefly)

The US ADA, the EU Accessibility Act, the UK Equality Act, and similar laws elsewhere all increasingly require web accessibility for businesses serving the public. Lawsuits and demand letters have been growing 20-30% year over year. The good news: a site that meets WCAG 2.1 Level AA is generally compliant in most jurisdictions.

The performance bonus

Accessibility fixes overlap heavily with performance and SEO fixes. Proper headings help search engines and screen readers equally. Alt text helps image search. Fast-rendering text helps everyone.
