Select Themes, then select the new theme and click the Switch Theme button in the lower-right part of the panel to switch the theme dynamically. Any theme developer who wishes to make a theme widely available to users must create a theme installation . The theme installation includes files that tell the chrome registry about the theme, about which components it affects, about the author, the files it comprises, and other important metadata. This section shows some examples of themes that third-party developers have already created for Netscape 6. As you can see, the theme technologies in Netscape 6 give web developers considerable breadth in the look of the interface.
Themes can be serious, simple, or playful.
A single, overall theme is made up of many skins. The Navigator component's skin, for example, described for the most part in navigator.css , is a part of the overall Modern theme of Netscape 6. Following this definition, the Modern theme may be made up of as many as 20 or 30 different skins. Once you become familiar with the power of cascading style sheets and use them to style the Netscape 6 user interface, you may begin to feel that there is nothing that can't be changed or manipulated with this technology. While menus and buttons cannot be changed structurally in the process of editing a theme, you can, of course, change their appearance.
