Specify whether to generate named CSS rules.
Named CSS rules are CSS rules generated from the formatting styles defined in templates. When such a style is assigned to a template component, the HTML tags generated by that component can be assigned with the CSS rule generated from that style. The class selector assigned to that CSS rule is specified in the template style itself (or derived from its name). Therefore, it has a constant (predictable) relationship with both the particular CSS property set produced from that style and the particular output structures where that CSS rule is applied. This opens a possibility to substitute the generated named CSS rules with the custom ones.

Please note that named CSS rules are not required for proper HTML output and will only increase its size. You need named rules only when you want to style the generated HTML documentation with your own CSS properties/rules.

Possible Values:
"none"
Disable the generation of named CSS rules.
"all"
Generate all named CSS rules possible.

When this setting is selected, almost all template formatting styles involved in the generation of the particular HTML output will be rendered into named CSS rules.
