CSS Description Types
Cascading Style Sheets (CSS) is a language that is used to create one or more documents that control the appearance of some or all the pages at your Web site (Bojack, 2007). CSS styles have three categories: external, embedded, and inline. Each of these categories has its own pros and cons to using them. Each one is chosen to use based on the circumstance of what you are trying to achieve on your Web page.

The pro and con to using this style is that inline styles override both external styles and embedded styles on your Web page. If you use too many of these you can lose the ability to change your format globally later which is the con. If you need to constantly update one line of text (sales information) you can use this style to go in and only change what you need...
