Millionare,
CSS is basically a codified language that individuals can use to state rules that determine the style, dimensions, color, placement and other characteristics in which selected elements for a web page will be displayed. These rules must be written in accord with an exact order of syntax and the selection of the right characters, numbers, and symbols in order for them to function. If placed in an external Style Sheet such rules can control the display of selected elements throughout an entire website of numerous pages. The use of these codes simplifies the design of websites and web pages and enables webmasters and other web authors to separate their design styles from the content that they write or publish. The placement of such rules determines what elements they control, and this placement can be made in a cascading level on web pages. This is from an external sheet to a rule that is embedded in the head section of a file to a rule that is place inline in the body of a file. It may take you awhile to learn this language, but it certainly makes publishing pages on the internet much easier and more attractive than trying to do this without such rules. All of the tutorials and books regarding CSS can help you to understand the language and how to use its particular characters, but you’ll learn more by just starting to use CSS in your blog or other web publications. Good luck with it!
