Cascading Style Sheets Introduction
What is CSS?
Invented in 1997, Cascading Style Sheets (CSS) are just now starting to be widely used among browsers and Web developers are learning to be more comfortable with them. Those of you who use HomeSite 4.0 know that they are eventually going to take the place of tags such as FONT, which have been deprecated in HTML 4.0.
CSS Syntax
When you create a style sheet, you need to make sure that the syntax is correct. You will find that CSS is a fairly easy language to learn, but it has many applications.
Placing CSS in a Document
Style sheets can be placed in three places in a document, in the HEAD, in an external file, or within an individual tag. Style calls placed within an individual tag will only affect that tag, while other style calls affect the entire page or any page that loads the style sheet.
An Explanation of “Cascading”
Cascading is something that makes CSS even more powerful. Learn what it means for a style sheet to “cascade”.
Your First Style Sheet
As I said above, Cascading Style Sheets are fairly easy to use and apply. After only one lesson you will have created a style sheet on a Web page.
