Cascading Style Sheets: "Syntax"
This chapter demonstrates many intermediate uses of CSS that we will address in later Units. The key thing that it enables you to do is create your first stylesheet.
Create a file called "mystylesheets.css" in the directory with "index.htm" and copy-and-paste the declaration and style rules from this chapter. This CSS file is not yet linked to your HTML file, so it will not change how your HTML file appears in the Web-browser. That is the next step.
