If you're like most Web developers, when you were first learning HTML, you probably spent a great deal of your time playing around with your browser. The fact that you could simply do a "View Source" and see how an interesting web page was implemented was one of the things that helped HTML catch on so quickly. This "code sharing" is undoubtably one of the reasons the Web was able to grow as quickly as it did.
Unfortunately, these days it's not so easy to take a look at the magic going on behind the scenes of the average web page. With the emphasis on usability and appearance, the previously simple HTML has become incresingly difficult to read and these days most web pages are made up of a combination of several files and use often use as much CSS and client-side script as they do HTML. Using "View Source" simply doesn't cut it anymore. Luckily Microsoft has realized this fact and is building a tool to help developers analyze these increasingly complex web documents. It's called the Internet Explorer Developer Toolbar. In this article I'll give you a quick introduction to this powerful new tool and examine some of it's most useful features.
These features enable you to:
1 Explore and modify the document object model (DOM) of a Web page.
2 Locate and select specific elements on a Web page through a variety of techniques.
3 Selectively disable Internet Explorer settings.

5 Outline tables, table cells, images, or selected tags.
6 Validate HTML, CSS, WAI, and RSS Web feed links.

8 Immediately resize the browser window to a new resolution.
9 Selectively clear the browser cache and saved cookies. Choose from all objects or those associated with a given domain.
10 Choose direct links to W3C specification references, the Internet Explorer team weblog (blog), and other resources.
11 Display a fully featured design ruler to help accurately align and measure objects on your pages.
