Website Accessibility Basics Every Builder Should Ship

Accessibility has a reputation as a compliance chore, but the basics are neither hard nor expensive — they are mostly using HTML the way it was designed. And every one of these fixes also improves your site for tired users, bright sunlight, slow connections and search engines.

The baseline checklist

• Contrast: 4.5:1 minimum for body text — check your grey-on-grey captions, they are usually the offender
• Alt text: describe meaningful images; use alt="" for decorative ones so screen readers skip them
• Keyboard: tab through your entire site — everything clickable must be reachable and usable
• Focus states: never remove the outline without providing a visible replacement
• Semantic elements: <button> for actions, <a> for navigation — clickable divs are invisible to assistive tech
• Forms: every input gets a <label>; placeholder text is not a label

What about animations?

Motion is an accessibility surface too: vestibular disorders make parallax and large sudden movements genuinely nauseating for some visitors. The fix is one media query — prefers-reduced-motion — that swaps animations for instant or fade-only states when the visitor's OS requests it. GSAP makes this clean with matchMedia, and Scroll Animation Mastery treats reduced-motion fallbacks as a core part of the craft, not an afterthought — every technique in the course ships with its accessible variant.

During the build, not after — retrofitting semantics and focus management is many times the effort of typing the right element first. Add a five-minute pass before every launch: tab through the page, run one contrast check, toggle reduced-motion in your OS and reload. The Pre-Launch Checklist bakes these checks into a repeatable launch routine alongside SEO and performance, so accessibility stops depending on memory.
