Dreamweaver comes with several professionally developed page layout and design element files. You can use these sample files as starting points for designing pages in your sites. When you create a document based on a sample file, Dreamweaver creates a copy of the file.
You can preview a sample file and read a brief description of a document’s design elements in the New Document dialog box. In the case of CSS style sheets, you can copy a predesigned style sheet and apply it to your documents.
