A clear and usable website.

We want this website to work for as many people as possible. If you have difficulty accessing information or using a feature, email [email protected]. Tell us which page or task caused the problem and, if useful, the device or assistive technology you were using.

How the site is built

The pages use semantic headings, visible keyboard focus, labelled form fields and a skip-to-content link. Menus and frequently asked questions can be operated with a keyboard. Layouts adapt to smaller screens, and the site respects a preference for reduced motion.

Articles and guides are available as web pages. Working guides can also be downloaded as PDF or editable Markdown, or printed from the browser. Wide reference tables can be scrolled horizontally.
