Cascading style sheets
Cascading style sheets (CSS) are used in this site to separate content from the display. The CSS contains positioning, layout, font, colours and style information for the entire web site.
Separating style from content makes life very easy for visitors who prefer to view only the content of a web page, or to modify the content. These could be blind or partially sighted people who might use a screen reader to interpret a page.
CSS also reduces the size of the HTML files. The CSS file is downloaded just once by the visitor's browser and re-used for different pages on a web site. This reduces the bandwidth requirements for your server and also ensures a faster download for your visitors.
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 on this site include descriptive attributes. Purely decorative graphics include empty alt attributes.
