CSS Explained

Pixelwave Web Design prides itself on its friendly helpful nature.
I understand that many of the terms used by website design professionals are alien and difficult to understand. These 'Essential' articles explain some of the basic terminology you may hear within the world of website design.

CSS Explained

CSS is an acronym for Cascading Style Sheets. It is one of the scripting (or coding) languages used by website designers to build your webpages.

CSS is designed primarily to enable the separation of document structure (written in HTML or a related language) from document presentation and layout (written in CSS). This separation provides a number of benefits, including:

  • Improved content accessibility
  • Greater flexibility and control in the specification of presentational characteristics
  • Reduced complexity of the structural content
  • Reduced maintenance and update costs
  • Reduced filesize and faster page loading

CSS style information can be either attached as a separate document or embedded in the HTML document. Different styles can be applied depending on what media is being used. For example, the screen version may be quite different from the printed version. This allows authors to tailor the presentation appropriately for each kind of media.

The World Wide Web Consortium (W3C) which establishes the specifications and guidelines for technologies on the web recommended the use of CSS in 1996 and CSS2 in 1998.CSS3 is currently under development.

Many web designers still use HTML for layout and presentation, and I must admit to having used it in that way in the past. Here at Pixelwave Design I now however use HTML or xHTML for structural markup only and CSS for presentation and layout.
