To preview how your page will look on the web, click on the “browse” icon in the toolbar at the top of the window. This will open a browser window so you can see how your page will appear after you load it on to a web server and make it viewable on the world wide web. REMEMBER, the preview function DOES NOT mean your page is on the web.
You can tell that the page is not on the web because when you look in the address bar you see that a file path beginning with C:/ is displayed, meaning that the file is stored on your local hard drive. If it were on the web the URL beginning with http:// would be displayed.
