The Document window shows the current document. You can select any of the following views:
Design view A design environment for visual page layout, visual editing, and rapid application development. In this view, Dreamweaver displays a fully editable, visual representation of the document, similar to what you would see when viewing the page in a browser. You can configure the Design view to display dynamic content while you’re working on the document.
Code and Design view Lets you see both Code view and Design view for the same document in a single window.
