WCAG Explorer (beta)

This resource is designed for anyone eager to master digital accessibility. Explore WCAG success criteria through clear, easy-to-understand descriptions. We owe a special "hat tip" to Johannes Lehner’s WCAG Card Deck, which served as the inspiration for this project.

We plan to expand this library over time, so please check back regularly for updates.
