Cascading Style Sheets

Cascading Style Sheets, also known as CSS, is a style sheet language that we use to describe the presentation semantics(look of the page, design of the page)

It can be attach to HTML, XHTML, XML, SVG, XUL, etc.

CSS is the scheme of your future website to determine which style rules to apply if more than one rule matches against a particular element.

CSS gives us the ability to shorten our code and not have to specify things on every single page for every single thing. For example, CSS allows us to have templates with labels. We can change fonts and colors and styles with a single flag. So we don't have to go through the hassle of writing out the code to change the font, make it bold, make it bigger, or smaller, or different colored, etc.

CSS specifications are maintained by the World Wide Web Consortium (W3C). Internet media type (MIME type) text/css is registered for use with CSS by RFC 2318
