The Open button is used to open an existing HTML file into the page designer. This is used when you’ve already created your HTML page using a program that creates Web pages, like FrontPage. The ability to import such pages into the designer is useful in companies that have a Webmaster on staff, who creates Web pages for the company, or when you wish to hire Web page authors to create your pages. By using the Open button, you can import these pages and then assign code to specific elements of the page.
