The Cascading Style Sheets CSS model allows you to define styles within or independent of your Web pages and to apply these styles to your Web pages in conjunction with HTML formatting. A style is simply a rule that associates display properties such as bold and blue with a particular HTML tag. The simplest way to define an internal style is to insert the style definition into your document. For example to specify that a single heading is to be both bold and blue you can type. h2 style color blue font-style bold From Birth Until Now h2 . This style only applies to the text between the h2 and h2 tags. To force all of your h2 level headings to be bold and blue you can type the command h2 font-weight bold color blue within the head of your document.

To create a separate style sheet you must create a file that contains the style definitions that you want to use. You identify this file with the extension .css. A CSS file contains style definitions such as the following h1 font-weight bold color black h2 font-weight bold color blue You can then use a link or an @import command to use your cascading style sheet in your Web pages.
