01 The minimum standard
Text contrast, a visible focus state, logical tab order, field labels, alt text for meaningful images, correct H1–H3 headings, and never relying on color alone for error states.
02 Components that break most often
Custom selects, modals without a focus trap, sliders without ARIA, icon buttons without aria-label, animations without prefers-reduced-motion support.
03 Business impact
An accessible site is more convenient for everyone: better SEO through semantics, fewer form abandonments, and a stronger brand of responsibility. Add a11y to your definition of done before release.
