Cascading Style Sheets: "Applying CSS to HTML and XHTML"
This chapter describes three different ways that CSS can be used with HTML. Keep these questions in mind: Which of these methods abstracts presentational markup from content to the greatest degree? Why is this an advantage? Note that inline presentational markup is required by some content management systems, while others provide a place to edit linked cascading style sheets. When given the option, it is always best to modify the presentation of an HTML file using external linked CSS. For the purposes of the stand-alone site you will develop in conjunction with this course, you will use external style sheets.
