Accessibility shouldn't be an afterthought — it should be the foundation. This episode breaks down why bottom-up web development produces more inclusive, legally sound, and higher-performing websites than the industry's default top-down approach.

Show Notes

Web accessibility is too often treated as a finishing touch — something to address once the design is locked and the code is shipped. This episode of DEV.co challenges that habit directly, making the case that building accessible websites from the ground up isn't just better ethics, it's better engineering. Drawing from the DEV.co article on bottom-up accessible web development, the episode walks through why the sequence of your development process determines the quality of what you deliver.

Here's what the episode covers:

  • Top-down vs. bottom-up development: Most teams start with branding and aesthetics, leaving accessibility as a retrofit — bottom-up flips that sequence so accessible structure comes first and everything else is built on top of it.
  • The real scope of accessibility: It extends well beyond screen readers — motor impairments, cognitive differences, hearing loss, and situational limitations all factor in, and nearly 43% of users report finding most websites difficult to use.
  • Screen reader testing as a baseline: With over 7.6 million Americans living with a visual disability, running screen reader tests — ideally with real users — before launch is one of the highest-return investments a developer can make.
  • Legal exposure is real: The ADA applies to public-facing websites, and landmark cases like the 2022 Domino's Pizza settlement signal that inaccessible builds carry genuine financial and reputational risk for developers and their clients.
  • Practical starting points: Learn accessible typography and color contrast fundamentals before opening a design tool; use heading hierarchy intentionally; and treat every dynamic feature — auto-refreshing feeds, focus-trapping modals, uncontrolled carousels — as a potential barrier until proven otherwise.
  • Accessibility as a competitive advantage: Sites built to be inclusive by default convert better, build more trust, and hold up under scrutiny — making accessibility a business argument as much as an ethical one.

What is DEV?

Software and web development from the side that has to ship it and then live with it. Architecture decisions with a cost attached, scoping, technical debt, hiring and vendor selection, and the AI tooling question every engineering team is now answering whether they planned to or not.

Each episode takes one decision — rewrite or refactor, framework choice, build versus buy, how to scope a fixed-bid project honestly — and works through the tradeoffs, including the ones that only show up in year two. Written for engineering leads, technical founders and the people who fund them. Five or six minutes, no hand-waving.

Topics include rewrite versus refactor, build versus buy, scoping fixed-bid work honestly, technical debt you should keep, framework and platform choices, hiring and vendor selection, code review culture, and where AI tooling actually helps.
