CAIRO Website Style Sheets

Varying the Appearance of the CAIRO Website

This page allows you to select the style to be applied to this website. The different styles are based on the seasons: Autumn uses autumnal browns and oranges, winter uses cool colours such as white and shades of blue and so on. The styles use different fonts so you may find that one combination of fonts and colours is easier to read on your computer's monitor than another.

How is it done?

This website uses CSS (cascading style sheets) to separate content from layout. All text was prepared using a plain-text editor; no fancy HTML editors such as FrontPage or DreamWeaver were needed or used. Nor does this site use frames or tables. The navigation menu, mouse-over effects and layout are all achieved by CSS.

CSS is a useful technology. If you want to see more, visit CSS ZenGarden website. All Zen Garden examples use the same html text, only the CSS varies.

CSS Requirements

In order to use the Seasons stylesheets, you need the following browser options:

Cookies

There is a lot of paranoia expressed about cookies, but in fact they are harmless. Cookies are used by this website to store the name of the style sheet that you have selected, so that it can be re-selected automatically for subsequent pages and the next time that you open this web site.

A web site can only access its own cookies. Reading or changing another site's cookies is prevented by your browser. There is also a limit to the total amount of space that cookies can occupy on your computer (typically 1.2mb), a trivial amount on a modern PC's hard disk. With modern browsers you can go to Options and view all of the cookies stored on your PC.

JavaScript

JavaScript is the programming language used to create the cookie and to pick up the currently active style sheet.

If Javascript is not enabled then you will not see any change when you click on the season items in the menu. If javascript is enabled, but cookies are not then you will see a change when you click on the season button, but the change will be lost as soon as you load another page.

The default style is the one named Autumn. If you cannot access the other styles then autumn will be the one that is used.
