Answer - There are different ways to apply CSS to a HTML document with a stylesheet, and these different ways can be combined: * inline (internal) (Deprecated for XHTML) * embedded (internal) * linked (external) and * @import (external) Note: An external stylesheet is a text file that contains only CSS Styles. HTML comments are not supposed to be in there and can lead to misinterpretation (> is the CSS "Child" selector!).
