Definition
Designing and developing websites that are usable by people with disabilities, following WCAG guidelines.
In Depth
Web accessibility covers screen reader compatibility, keyboard navigation, color contrast, alternative text for images, ARIA labels, and semantic HTML. WCAG 2.1 AA is the widely accepted standard.
Example Usage
Adding aria-labels to icon buttons, ensuring 4.5:1 color contrast ratios, and supporting keyboard navigation throughout the dashboard.
Business Context
Accessibility is both a legal requirement (ADA compliance) and good business — accessible sites reach a wider audience and often have better SEO due to semantic markup.
