Picture two versions of the same sentence. One says, "Utilise the aforementioned functionality in the event that remuneration has not been received subsequent to the due date." The other says, "If you have not paid by the due date, use this feature." Same information, same code, same design. One of them excludes readers before they finish the first line.
Most accessibility barriers people picture are technical: a missing alt attribute, a button a keyboard cannot reach. But a huge share of the barriers a reader actually meets are written, not coded, dense jargon nobody defines, a link that says "click here" five times on one page, a heading that reads as a pun instead of a signpost, a photo captioned only with its camera filename. None of those need a developer to fix. They need a content author who knows what to change.
That is the promise of this course. It is built for anyone who writes for a website or app, editors, marketers, support staff, and it needs no code. Each lesson gives you one concrete habit, and the method stays the same throughout: pick one real page you own and rework it as you go, so you finish with a genuinely improved page and a repeatable checklist, not just theory.
A developer can ship a perfectly coded page, and your words can still turn a reader away, or quietly welcome them in. Content decisions are accessibility decisions, made by whoever writes the words, no code required.
