Answer
Accessibility best practices make content and controls usable through different senses, devices, and assistive technologies. • Use semantic HTML, logical headings, labels, alternative text, and descriptive links. • Support keyboard operation, visible focus, zoom, reflow, and sufficient contrast. • Use ARIA only when native HTML cannot provide the required semantics.
💡 Simple Example
<nav aria-label="Main"><a href="/courses">Courses</a><a href="/contact">Contact</a></nav>
