ADA vs. WCAG: understanding the difference between accessibility law and the technical guidelines developers use to build accessible websites.<\/figcaption><\/figure>\n\n\n\n

If you’ve ever Googled “ADA compliant website” at 11 PM in a mild panic because a client mentioned a lawsuit, welcome. You’re in good company. Half the internet is having this exact crisis right now, usually right after someone from legal forwards an email with the subject line “URGENT – please read.”<\/p>\n\n\n\n

Here’s the thing nobody explains clearly enough: ADA and WCAG are not the same thing<\/strong>, and mixing them up is like confusing “the speed limit” with “the laws of physics.” One is a rule humans made. The other is closer to how the universe (or in this case, assistive technology) actually works. You need both, but they do very different jobs.<\/p>\n\n\n\n

Let’s sort this out \u2014 legal side first, then the part you’re really here for: what to actually put in your HTML.<\/p>\n\n\n\n\n\n\n\n

ADA: The Law That Doesn’t Tell You What to Build<\/h2>\n\n\n\n

The Americans with Disabilities Act<\/strong> is a U.S. civil rights law from 1990. It says people with disabilities can’t be discriminated against, including when it comes to “places of public accommodation.” Originally that meant ramps into buildings and accessible bathroom stalls. Over the last couple decades, courts have increasingly decided it also means your website<\/em>.<\/p>\n\n\n\n

Here’s the plot twist that trips everyone up: the ADA doesn’t contain a single line of technical web accessibility requirements.<\/strong> No pixel counts. No contrast ratios. No “thou shalt label thy form inputs.” It just says: don’t discriminate, provide equal access. That’s it. It’s a principle, not a spec sheet.<\/p>\n\n\n\n

Which is a bit like your boss telling you to “make the app better” with zero further detail. Technically an instruction. Not exactly actionable.<\/p>\n\n\n\n

So how does anyone know what “equal access” means in code? That’s where the other half of this article comes in.<\/p>\n\n\n\n

WCAG: The Actual Instructions<\/h2>\n\n\n\n

The Web Content Accessibility Guidelines<\/strong>, written by the W3C (an international standards body, not a government), are the technical specification that ADA never bothered to write. WCAG is organized into three levels:<\/p>\n\n\n\n
