About This Web Site: Style

The style or presentation of the web site is controlled by CSS (Cascading Style Sheets) in the form of a series of external files. These CSS files are stored in the browser’s cache after they have been downloaded once. The separation of style from content greatly enhances the download speed and rendering of pages.

Separation of presentation and content also allows structure to ‘degrade’ gracefully in non-CSS browsers such as Lynx. Users of GUI (Graphical User Interface) browsers can also substitute their own style sheets if required.

CSS mark-up is based on the World Wide Web Consortium (W3C) CSS 2.1 Recommendation while taking into account Internet Explorer’s limited support for this level: the latest version, Internet Explorer 6.0, only has full support for CSS 1.0.

One feature of CSS, which is also a recommendation of the W3C Web Accessibility Initiative (WAI) Guidelines, is the appropriate rendering of quotations using the quote and blockquote tags.

The quote and blockquote tags are important structural elements for users of screen reading software so we have used them in spite of Internet Explorer’s inability to process them properly.

Quotations are represented in Internet Explorer by rust-coloured text without the quotation marks. We are aware that the use of colour in this instance may compromise legibility for users who have difficulty distinguishing colour. In this instance we should stress that other GUI browsers and also the Lynx text browser render quotations appropriately.

It is hoped that version 7.0 of Internet Explorer will provide better support for quote and blockquote tags as well as other features of CSS 2.1 when it is shipped later in 2005.

Note: All stylesheets have been validated by upload using the W3C CSS Validation Service.
