Screen reader compatibility

This website works with screen readers which can read and recognise links, tables, header, lists and forms.

Web pages sent to print are formatted appropriately. Areas of the page which are not useful in print, such as navigation, are removed. If you prefer a different style you could select and copy the text, paste it into a word-processing application, change the style and print it.

How we built this site

Code specifications

The hypertext markup language (HTML) used to structure web pages complies with XHTML 1.0 strict specifications. The cascading style sheets (CSS) used to style web pages comply with CSS 2.1 specifications.

These web pages will look consistent and work in a similar way across a wide range of browsers and devices, now and in the future.

Customisable design

CSS provides the default design for web pages including text size, colour, images and layout. Customise this site allows you to adjust the design easily according to your preferences.

Navigation

Navigation menus are styled consistently to improve usability. These include

• ‘Skip to content’ link providing quick access to web page content for screen readers and keyboard users, by bypassing navigation menus
• group of links to the sitemap, A-Z and search, at the top right of every web page
• group of links to section pages and the top-level section page, on the right side of every web page. The current page title is highlighted to reflect your current location
• links to subpages in the right side navigation, where relevant
• icons to help identify warnings, actions, site features and document types such as Portable Document File (PDF)
• group of links at the bottom of every web page providing access to Back to top, Customise this site, Print this page, Site feedback, How this site works
