You also should set some basic properties for your page. The most important page property is the document Title, which is the name of the page the displayed in the blue bar at the top of a browser, the name used by a search engine if it indexes your page, and the name of a bookmark if someone bookmarks your page on their browser.
You type in the name of a page directly from within DreamWeaver by using the Title field at the top of the document window (shown here as Untitled Document).
The default name of "Untitled Document" is useless to Web surfers and search engines. So be sure to give every page on your site a unique title! Doing so will also win you big points with your local webmaster.
Other page properties can be set by going to menu at the top and selecting Modify...Page Properties, or in the Property panel by clicking on the button labeled Page Properties... (you also can use the Cmd-J (Mac) / Ctrl-J (Windows) shortcuts).
You'll get a properties panel similar to this:
This panel again can be used to type in the document title.
You also can set margins on the page so your text and other elements do not butt up against the edge of the page. You set margins by typing a number into the margin fields - the higher the number the bigger the margin.
The Left Margin field only adds a margin on the left of the page and the Top Margin field only adds a margin to the top of the page. The Margin Width field will add a margin on both the left and right sides of a page. And the Margin Height field will add a margin to the top and bottom of the page.
