Many Internet users with disabilities find website difficult or even impossible to use simply because of the way they are designed. This website has been designed to be as accessible as possible and to be compatible with the types of adaptive technology used by people with disabilities, including screen readers. As such, visitors can control the size of the text and can use ‘access keys’ on the keyboard rather than the mouse to navigate through pages.
The stylesheet uses relative font sizes and is written to display pages correctly in most commonly used browsers. In early versions of browsers and browsing devices that do not support stylesheets at all, the flow of the content has been tested to ensure it entirely retains its sense.
Foreground and background colours contrast well throughout the site, with the majority of content appearing black on white.
The site is free of frames and uses a cascading style sheet for visual layout. Tables are used for tabular data, but we have avoided using them to dictate the layout of a page wherever possible.
Internal Navigation Links
At the start of every page are invisible links providing direct access to content, navigation and the accessibility statement, each with access keys. When keyboard navigating, however, the links become visible.
External website links on the site will open a new browser window and most links have title attributes, which describe the link in greater detail, and in the majority of cases the text of the link already fully describes the target. Wherever possible, links are written to make sense out of context.
Link text is never duplicated. Two links on the same page with the same link text always point to the same address. External links on the site will open a new browser window. New windows are never opened without either a warning in the text or in the ‘title’ attribute of the link.
All content images on the site include descriptive ALT attributes. Those purely decorative graphics or used for layout include empty ALT attributes.
