When I began my journey into accessible design, I quickly realized that finding relevant information about accessibility was not easy. So many articles: some were contradicting, some seemed outdated, or only spoke about one aspect of accessibility (most of the time about color-contrast). Some people told me RTFM, aka the Web Content Accessibility Guidelines (WCAG 2.0). I tried, but I didn’t feel it was fit for beginners or people who are not familiar with web development.
Online courses and webinars are also fantastic sources to understand the WCAG principles better. Again, the same question came back: where to start, what are the classes adapted for those unfamiliar with design or front-end development?
