Welcome
Be welcome thee who enter the realm of CSS
This site is all about CSS, the abbreviation for Cascading Style Sheets. CSS is a style sheet language used to describe the presentation (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can be applied to any kind of XML document, including SVG and XUL. In human speak, all this means that styles define how to display markup elements.
CSS is designed to separate document content (written in HTML or a similar markup language) from document presentation, including elements such as the colors, fonts, and layout. This separation can improve content accessibility, provides more flexibility and control in the specification of presentation characteristics, enables multiple pages to share formatting, and reduces complexity and repetition in the structural content. Again, in human speak this means that Style Sheets are a very powerful tool for the Web site developer. They give you the chance to be completely consistent with the look and feel of your pages, while giving you much more control over the layout and design than straight markup will ever do.
CSS can also allow the same markup page to be presented in different styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices. While the author of a document typically links that document to a CSS stylesheet, readers can use a different stylesheet, usually one on their own computer, to override the one the author has specified.
