Summary

Accessibility ensures that the page is accessible to everyone, including screen reader users and keyboard users. This material covers alt text, heading structure, color contrast, and ARIA attributes. Accessible pages are also generally more search engine friendly and more structured.

Key points

Contrasts of the text are at least 4.5:1 for normal text (WCAG AA)
ARIA like the aria-labels give accessible names to elements without text visible
