All pages on this site validate as HTML 4.01 Strict.

All pages on this site use structured semantic markup. H2 tags are used for main titles, H3 tags for subtitles.

Structural Markup

A header bar that includes the main navigation

A “side bar”

A main content area

A footer

When CSS (Cascading Styles Sheet) are not applied to a document (or when using a screen reader), the 4 areas are read in the above order.


All form controls are appropriately and explicitly labelled.

We provide an email address as an alternative form of access for our online forms -it is in the footer on every page.

Visual Design

This site uses cascading style sheets for visual layout.

This site uses only relative font sizes in the main body text and headers, compatible with the user-specified “text size” option in visual browsers.

If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
