CSS

A web design term. Short for 'Cascading Style Sheet'.

CSS was developed to allow the designer to define the way a web page is presented to the user, for example there are CSS commands for the colour and size of text, the positions of images and the width of text blocks.

CSS can be stored in a separate file to the web (.html) page, this file has the .css extension. This has the advantage of allowing other html files to also refer to it. This means that a change to that single CSS file can immediately affect the look and feel of the related web (html) files.

CSS commands can also be written right into the the web page itself, although these commands cannot be shared with any other web page.
