Procedural knowledge for ensuring frontend interfaces comply with WCAG standards and are usable by everyone.
Enable the Developer and QA Engineer roles to enforce accessibility best practices, ensuring the application is usable via screen readers and keyboard navigation.
Step 1: HTML Structure
- Ensure proper heading hierarchy (h1 -> h2 -> h3) without skipping levels.
- Use semantic tags (`<nav>`, `<main>`, `<article>`) instead of generic `<div>`s.
- Ensure all interactive elements use `<button>` or `<a>`.
Step 2: ARIA Attributes
- Add `aria-label` or `aria-labelledby` to elements without visible text.
- Define `aria-expanded` and `aria-controls` for dropdowns and accordions.
- Avoid redundant ARIA attributes that conflict with semantic HTML.
Step 1: Keyboard Navigation
- Ensure every interactive element is focusable (`tabindex="0"` if custom).
- Verify a visible `:focus` state exists for all interactive elements.
- Ensure no "keyboard traps" exist.
Step 2: Visual Constraints
- Check color contrast ratios (minimum 4.5:1 for normal text).
- Ensure `alt` text is descriptive for meaningful images, and empty (`alt=""`) for decorative ones.
