Chapter 25. Using Layers > Introduction to Layers

Introduction to Layers

In the early days of Web sites, Web developers were content with having a Web page with columns of text for their hyperlinks. Web pages were boring and drab, but they served their purpose. As the Internet became more popular, Web sites became more interactive and dynamic. Instead of plain text and graphics, it is much more common now to see dynamic graphically-oriented Web pages with content that changes in real-time as you interact with the page.

A Web developer can use many techniques to create a Web page in which certain areas of the Web page change as the user interacts with it. Many Web developers use <DIV> tags to implement this kind of funationality because by using the style attribute of the <DIV> tag, you can easily control the <DIV> tag's position, size, and many other attributes.
