You can create an entire web site in Dreamweaver without seeing the behind-the-scenes code, or HTML. But if you understand HTML, you can copy the code from one page to another, which allows you to make changes more quickly than if you used Dreamweaver’s other features. You can also view the code of pages on the web to learn techniques that other publishers use to lay out their content. You can then copy that code and use it in your own site. Later in the exercise, you’ll copy code from your own site; on the last page of this document are instructions on how to view the HTML of other web pages.

Now that you’ve made formatting changes, you can compare the way your page looks in Internet Explorer with the behind-the-scenes code, or HTML. First, save your document and preview it in Internet Explorer.

1. Save your work.
2. From the File menu, Preview in Browser submenu, choose iexplore, or press F12. Internet Explorer reloads your page.
3. Look at the different formatting on your page.
4. Switch back to Dreamweaver.
5. To view the HTML code click on the Code tab shown below.
