How the pages behave

Headings run in order and describe the section under them, images carry text alternatives, and the text stays readable against the colour behind it. Links show a visible outline when reached by keyboard.

Where this falls short

Technical subjects are written as plainly as the subject permits. That is a limit of the subject, not a design choice.

Amendments

Any change is made on this page rather than notified separately. The date at the top records when this text was last set.
