Theme refers to the look or overall style of an application such as a web browser.
In Netscape 6, the theme includes the images, colors, styles, positioning, and to some extent the behavior of elements in the user interface, as described later in this guide. By altering one or more of the elements that affect the theme, developers can significantly modify the Netscape 6 theme or create an entirely new theme without altering the basic structure and function of Netscape 6. The theme of Netscape 6 is separate from its structure and function because of the way in which the interface is defined. By changing the CSS files or pointing to a different set of CSS files entirely, you can change the theme of the application without affecting the underlying structure or functionality. Table 1-1 indicates various technologies used in Netscape 6 and their affect on different aspects of the interface.
