Every diagram has a text result beside it
The planners and the price comparison use labelled controls, visible keyboard focus and written results, so no quantity or warning appears only in a picture.
What we build in
- Standard form controls with visible labels, all usable with a keyboard.
- A skip link, headings in order and a clear focus outline.
- Written summaries of quantities, assumptions, warnings and what each diagram shows.
- Pages that reflow on narrow screens and at high browser zoom.
- Error messages that name the measurement to fix.
What the diagrams don't do
They show a calculated layout. You can't edit them, and they aren't cutting or fitting instructions. If a diagram is hard to use, the results, notes and assumptions beside it give the same quantities and limits in words.
