Designed to reduce unnecessary effort.

What has been built in

• Semantic headings, landmarks and labels, with one h1 per page
• A visible skip link, and a focus indicator that meets contrast requirements on both light and dark sections
• Keyboard operation throughout, including the mapping tool, with Escape closing the mobile menu
• Responsive layouts that reflow without horizontal scrolling down to 320 pixels wide
• Text contrast of at least 4.5:1 for body copy, and information that never relies on colour alone
• No autoplay, flashing, parallax, pop-ups or continuously moving content
• Reduced-motion support for people who request it in their device settings
• A 30-second, low-capacity alternative to the longer mapping tool
• Plain-language summaries and explicit stopping points on every step
• Content pages that work with JavaScript switched off; the mapping tool degrades to a readable, printable list of questions

Text and zoom

Text uses relative sizing and should remain usable when enlarged. The smallest text on the site is around 12.5 pixels and is used only for short labels; body copy is larger. The layout is designed to reflow on mobile and at 200% browser zoom rather than requiring two-dimensional scrolling.

What changed in version two

• The focus indicator was changed from a pale coral outline, which did not meet the 3:1 non-text contrast requirement on light backgrounds, to a high-contrast dark ring that switches to the signal colour on dark sections.
• All small label text was raised to a minimum of 0.78 rem.
• Selected states in the tool now carry a tick or a control as well as a colour change.
• The mobile menu now traps focus while open, closes with Escape, and returns focus to the menu button.
• Progress through the tool is announced to screen readers through a status region.
• The current page is marked with aria-current and an underline.

Known limitations

The site has been checked with automated tooling and by keyboard, but automated checks and one person’s testing do not reproduce every combination of assistive technology, browser, device and cognitive access need. Specific things still to improve:

• No testing yet with real screen-reader users, which is the only test that really counts.
• The decorative contour graphic on the homepage is hidden from assistive technology rather than described, because it carries no information.
• The download control creates a plain-text file. On a shared device, consider whether saving it is appropriate.
• Print styles are provided but have been checked in a limited number of browsers.

Ongoing review

Accessibility is treated as part of the product rather than a final checklist. Real-user testing—especially with neurodivergent adults using screen readers, keyboard navigation, zoom and the reduced-capacity route—is the next meaningful validation step. If something here does not work for you, that is useful information and it will be acted on.
