Accessibility

We recognise the importance of providing a website that is accessible by all users. As such we have made every effort to ensure that our site can be easily used by people with disabilities. To ensure we are as accessible as possible, we have designed our web site to comply with Conformance Level "A" of the W3C Web Content Accessibility Guidelines.

Navigation

A hidden menu has been placed at the beginning of each page to allow screen reader users to link to the main areas of the page.

A hidden link has also been provided at the beginning of each page to provide easy access to information on accessibility.

Access keys

The access key conventions used troughout this site are:

To use the accesskey in Microsoft Windows, press the ALT' key, plus the key indicated above, and then press the return key on your keyboard

Headings and navigation menus

HTML heading tags are used to convey document structure. H1 tags are used for main titles, H2 tags for subtitles etc.
Navigation menus are marked up as HTML lists. This ensures that the number of links in the list is read out at the start and it can be skipped easily.

Images

All images used in this site include descriptive alt tag attributes.

Colours

We have taken care to ensure that the site's font and background colour combinations contrast significantly and are effective in ensuring information is still clear when viewed in different colour combinations.

Font size

Most of the font sizes we use on our site are sizable: you can change the font size to make it either larger or smaller via your browser settings.

You can change the font size in the following ways depending on your browser;

• In Internet Explorer; select View, then Text Size, and then your preferred size.
• In Netscape; select View, then Text Zoom, and then your preferred percentage size.

Stylesheets

This site uses cascading style sheets for all visual layout. If your browser or browsing device does not support stylesheets at all, the use of structured semantic mark up ensures that the content of each page is still readable and clearly structured.

You can apply your own stylesheet onto this website by:

Internet Explorer

• select Tools, then Internet Options, then Accessibility;
• next click on any or all 3 checkboxes to ignore colours, font styles or font sizes;
• in the same window you can change your style sheet by clicking the checkbox that says, 'format document using my style sheet' then browse to your style sheet and click OK.

In Netscape

• select Edit, then Preferences and then Appearance;
• you will be given the choice to specify your own colours and fonts.

Tables

Most data tables have properly scoped header cells, to allow screen readers to render them intelligently. We have also ensured table summaries are used as well as captions where appropriate.

Tables used for layout use none of the above attributes to ensure that they are not confused with data tables.

Forms and fields

All forms fields follow a logical tab sequence to ensure easy navigation.

Most form fields also have ‘label’ and ‘id’ attributes to associate explicitly the form field with its label and to allow for easy entry of data.

JavaScript

The use of JavaScript has been kept to an absolute minimum. Where it is used then all pages and processes are still accessible should JavaScript be turned off.

Links

All links have been written to make sense when taken out of context. Where appropriate, we have also added link title attributes to describe the link in greater detail.

Copy

Abbreviation and acronym tags have been used where appropriate to ensure abbreviations and acronyms are given a full textual explanation. We have also ensured that blockquotes are only ever used for identifying quotations. They are not used for formatting purposes.
