The General tab of the New Document dialog box enables you to create a new blank page or use a predesigned page.
The list on the right changes based on your selection. A description, and, for most categories, a preview of the selected document also appear.
For example, you can make an HTML document XHTML-compliant by selecting XHTML 1.0 Transitional or XHTML 1.0 Strict from the pop-up menu. For more information, see About the XHTML code generated by Dreamweaver.
XHTML (Extensible Hypertext Markup Language) is a reformulation of HTML as an XML application. Generally, using XHTML lets you realize the benefits of XML, while ensuring the backward and future compatibility of your web documents.
For more information about XHTML, see the World Wide Web Consortium (W3C) website, which contains the specification for XHTML 1.1 - Module-Based XHTML (www.w3.org/TR/xhtml11/) and XHTML 1.0 (www.w3c.org/TR/xhtml1/), as well as XHTML validator sites for web-based files (http://validator.w3.org/) and local files (http://validator.w3.org/file-upload.html).
The new document opens in the Document window.
