Specify whether to generate the external CSS file (global style sheet).

When this option is selected (true), an external CSS file will be generated, which is placed in the output destination directory typically under the name 'stylesheet.css'. Most of the HTML formatting settings used in the generated documentation will be held in this file referenced from each HTML document via a <link> tag, e.g.:

<link rel="stylesheet" type="text/css" href="../../stylesheet.css">
When this option is unselected (false), no external style sheet file will be generated. In that case, all CSS rules used in the generated HTML will be defined locally within those HTML files themselves, inside <style> element.

Nested Options:
