WCAG, but in language I can understand

Designer/developer Martin Underhill has written “a single article summing up each success criterion (SC) in WCAG 2.1 in as close to a single paragraph as [he] can manage”, because the guidelines themselves are not the easiest read. He leads with a disclaimer that this is not aimed at any audience other than himself, and obviously for brevity a lot of SC exceptions are missing.

It’s a really useful overview – here are some examples:

  • 1.1.1 Non-text Content
    • Images should have descriptive (alt) text.
  • 1.3.2 Meaningful Sequence
    • The visual presentation of the content matches what’s read out by a screen reader.
  • 2.1.2 No Keyboard Trap
    • There shouldn’t be a situation where you enter a modal with the keyboard and can’t get back to where you were.

Alongside digitala11y.com, which does a similar thing but breaking each SC down into its own short article, there are now plenty of ‘simplified explanations’ of WCAG to refer to.
