The HTML Appearance Page Properties category lets you specify several basic page layout options for your web pages:
Background Image and Background specify a background image and background color for the page. See Setting a background image or background page color.
Text and Links define default colors for text, links, visited links, and active links (see Working with colors). You can also control these colors using CSS style sheets (see Applying a class style).
Left Margin and Top Margin specify the sizes of page margins in the body
tag, for Microsoft Internet Explorer only. Netscape Navigator ignores these values, using Margin Width and Margin Height instead. For best cross-browser results, provide margin values for both browsers instead of just one browser; fill in all four margin values instead of just two. To ensure that no margins appear in either browser, set all four values to 0. Dreamweaver doesnt display page margins in the Document window; to see the margins, use Preview in Browser.
