More about CSS rules
CSS rules can reside in the following locations:
External CSS style sheets are collections of CSS rules stored in a separate, external .css file (not an HTML file). The .css file is linked to one or more pages in a website by using a link in the
head section of a document.
Internal (or embedded) CSS style sheets are collections of CSS rules that are included in a
style tag in the
head portion of an HTML document. For example, the following example defines the font size for all text in the document formatted with the paragraph tag:
Inline styles are defined within specific instances of tags throughout an HTML document. For example,
<p style="font-size: 9px"> defines the font size for only the paragraph formatted with the tag that contains the inline style.
Dreamweaver renders most style attributes that you apply and displays them in the Document window. You can also preview the document in a browser window to see styles applied. Some CSS style attributes render differently in Microsoft Internet Explorer, Netscape Navigator, Opera, and Apple Safari.
