Accessible Web Design · Guide

Your website has to work for everyone. That’s not optional anymore.

Website accessibility protects your business legally and opens your doors to the 1 in 4 adults who have a disability. This guide covers what WCAG 2.1 AA actually requires, why overlays don’t save you, and how to fix the most common problems.

01 · The Legal Picture

Websites are places of public accommodation under the Americans with Disabilities Act. That ruling has held up across hundreds of cases. If your business serves the public — a restaurant, a salon, a contractor, a retailer — your website falls under the same rules as your physical location. You wouldn’t block a wheelchair ramp. A site that a screen reader can’t navigate is the same problem.

Overlays do not protect you

Accessibility overlay widgets — those small toolbar buttons that claim to “fix” your site automatically — do not make a site accessible. In 2023, over 900 businesses using these widgets were still sued, a 62% jump from 2022. Courts have consistently ruled that automated overlays do not satisfy ADA requirements. They patch the visible symptom. They don’t fix the underlying code.

WCAG 2.1 AA is the standard

The DOJ now explicitly requires WCAG 2.1 Level AA compliance for public entities under ADA. For private businesses, WCAG 2.1 AA is the de facto benchmark courts use to evaluate whether a site is accessible. It’s not a checklist you run once — it’s a set of technical standards that have to be built into the site from the start.

02 · Why It’s Also Good Business

Accessibility isn’t a cost. It’s a wider net.

1 in 4 U.S. adults has a disability. 71% of them leave a site that doesn’t work for them. That’s not a niche market — it’s a quarter of every person who might have looked you up. In Kingman, where roughly 26% of residents are over 65, that number is even more significant. Vision, motor, and cognitive changes come with age. A site designed with accessibility in mind serves that population by default.

The SEO overlap is real too. Semantic HTML, meaningful alt text, logical heading structure, fast load times — every accessibility best practice is also a search ranking signal. A site built to WCAG 2.1 AA is, by design, easier for both humans and AI to read.

03 · The Most Common Failures

95.9% of top websites have detectable accessibility errors. These are the usual suspects.

Issue · Who it affects · The fix

Missing alt text
Screen reader users
Add meaningful alt to all images. Use alt="" for decorative ones.
Low color contrast
Low-vision, outdoor mobile users
4.5:1 ratio for body text. 3:1 for large text.
No keyboard navigation
Motor-impaired users
All menus, modals, and forms must be reachable by Tab key.
Unlabeled form fields
Screen reader users
Use <label> or aria-label linked to every input.
No skip navigation
Keyboard and screen reader users
Add a "Skip to main content" link as the first focusable element.
Videos without captions
Deaf / hard-of-hearing users
Provide captions and transcripts for all video content.

“A WebAIM study found 95.9% of top websites had detectable accessibility errors — averaging 56.8 errors per homepage. Most were fixable in under an hour with the right audit.”

The Design Bureau · Accessible Web Design

Every site I build is WCAG 2.1 AA compliant. That’s the floor, not the ceiling.

Accessibility isn’t a bolt-on I add at the end. It’s built into the HTML from the first line — semantic structure, proper labels, contrast ratios, keyboard navigation, skip links. For existing sites, I run a full WCAG 2.1 AA audit, document every failure, and fix them. For new builds, compliance is standard across every tier.

What's included

Full WCAG 2.1 AA audit (existing sites) Included in all builds
Semantic HTML, skip links, ARIA labels Standard
Color contrast compliance (4.5:1 minimum) Standard
Keyboard navigation testing Standard
