How this is taught
01
People before rules
A guideline tells you what to comply with. A person shows you why it matters. Every idea here arrives attached to someone it affects.
02
Short lessons, real practice
Three to seven minutes, one idea, then a question with an explanation of why the answer is what it is. Getting it wrong is part of the design.
03
Plain English, honest sources
Written for people who are not developers, based on public guidance such as WCAG and WAI — with the links at the end, not in your way.
Sample lesson
Barrier, need, impact — three words, three different jobs
Get this one distinction and half of accessibility stops sounding like a foreign language. The lesson walks a single situation end to end, then asks you to sort a new one yourself.
