Browser Detection and CSS

CSS controls navigation displays

On loading, OmniHelp detects the browser in use, and selects the appropriate CSS files for displaying navigation labels and data, and topic content. Navigation displays are controlled by the CSS settings, as specified in ohctrl.css, the default stylesheet, and in the browser-specific variants for Netscape Navigator 4 (ohctn4.css), Netscape Navigator 6+ (ohctn6.css), and Internet Explorer 4+ (ohctie.css). The author (or user) is free to edit this CSS, and to produce more variants.

The CSS for displaying topic content is best supplied by the author or user, because it depends on the classes used in topic files. Again, the built-in browser detection offers the same variants listed above for NS4, NS6, and IE.
