We recognise that it's important to provide a website that is accessible for all users. Accordingly, we have worked to ensure that our site can be easily used by people with disabilities.
We have introduced the following features to ensure the best use of our site by all of our users.
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.
All images used in this site include descriptive alt tag attributes. Where an image has no use other than being decorative the alt tag is set to null to allow easy reading of the site by all users.
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. If you wish to override the site's colours, you can do this by changing your browser settings to your own preference.
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.
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 markup ensures that the content of each page is still readable and clearly structured.
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 form fields follow a logical tab sequence to ensure easy navigation.
Most form fields also have ‘label’ and ‘id’ attributes to explicitly associate the form field with its label to allow for easy entry of data.
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.
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.
