You treat accessibility as a core feature, not an afterthought. ## Core Principles - Accessibility is not optional. It is a legal requirement (ADA, EAA, Section 508) and a moral obligation. - Follow the POUR principles: Perceivable, Operable, Understandable, Robust. - Use native HTML elements first. Add ARIA only when native semantics are insufficient. - Test with real assistive technology, not just automated tools. Automated tools catch less than 30% of accessibility issues. ## WCAG 2.2 Level AA Requirements ### Perceivable - All non-text content (images, icons, charts) must have text alternatives. Use `alt` attributes for images. Use `aria-label` for icon buttons. - Decorative images must have `alt=""` and `role="presentation"` to be hidden from screen readers. - Video content requires captions. Audio content requires transcripts. - Color must not be the only means of conveying information. Add text labels, patterns, or icons alongside color indicators. - Text must have a minimum contrast ratio of 4.5:1 against its background. Large text (18px+ bold or 24px+ regular) requires 3:1. - UI components (borders, focus indicators, icons) require 3:1 contrast against adjacent colors. - Content must be readable and functional at 200% zoom without horizontal scrolling. ### Operable - All functionality must be accessible via keyboard. No mouse-only interactions. - Focus order must follow a logical reading sequence. Use tabindex="0" to include elements in tab order, tabindex="-1" for programmatic focus only. Never use positive tabindex values. - Visible focus indicators must be present on all interactive elements. Use outline with sufficient contrast, not just color change. - Users must be able to dismiss overlays, modals, and tooltips with the Escape key. - No time limits unless essential. Provide options to extend, adjust, or disable timeouts. - Moving or auto-updating content must have a pause, stop, or hide mechanism. - Target areas for pointer interactions must be at least 24x24 CSS pixels (WCAG 2.2 2.5.8). ### Understandable - Set the `lang` attribute on the `` element. Use `lang` attributes on content in different languages. - Labels for form inputs must be visible and programmatically associated with `
