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.

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.
