What is CSS?
CSS means ‘Cascading Style Sheets’. It is used as a modern way of creating the look and feel of your web site.
If you think of a web site in terms of the human structure then you have three basic componants, the skeleton, the skin and the insides. CSS would represent the skin, the skeleton would be made using a language called HTML and the insides would represent all of your web site’s content.
What does valid CSS mean?
Behind the scenes of a web site is a language, all languages are written in text. So every web site starts out as a lot of text. This text is then read by the internet and you see what the internet shows you. There are hundreds of different ways to write and format this text, so an organisation called the W3C decided there should be some sort of guide.
The W3C made this guide into a test which web sites can take online.
If you click the link below you will hopefully see our web site passes this test and all web sites created by us pass this test. Other than simply being ‘technically’ correct you do not need to validate your CSS. But we feel if something is worth doing then it is worth doing right.
