Two options for Cascading Style Sheets
There are a couple different options to apply CSS styles, and some are better than others. In order to declare styles in an unobtrusive manner, we want to link our HTML page to an external style sheet. This external text file contains all of our CSS style declarations, and can be linked to any HTML document to which we want to apply styles. Essentially we then have all of the flexibility of CSS with only a minimum of extra code added to our HTML document.
