Chapter 10. Frames
As you start to build bigger and more elaborate Web sites, you'll no doubt discover one of the royal pains that come with being a Web maven: getting a common element (like a navigation bar) to appear on every page in your site.
For example, you might decide to add a menu of links that let a visitor jump from one section of your Web site to another. You can place these links in a table or a <div> tag (two techniques demonstrated in Chapter 9). However, either way, there's a problemin order to show this menu on every page, you'll need to do a fair bit of copying and pasting. If you're not careful, one page will end up with a slightly different version of the same menu. And when you decide to make a minor change to the menu, you'll be faced with the nightmare of updating dozens of pages.
One way to tackle this problem is with frames , a sometimes- controversial HTML feature that lets you show more than one Web page in the same browser window. In this chapter, you'll learn how to use frames to tame large Web sites.
