When compiling any HTML based Help target and using Word source documents, Doc-To-Help produces a Cascading Style Sheet file (.css) based on the template that is attached to your Help target. This file governs the appearance of your HTML Help targets in much the same way as a Microsoft Word template governs the appearance of a Word document. In most cases, there is no need to do anything to the CSS file, Doc-To-Help modifies it as needed during each compilation of the Help target. This file is produced only if Word documents and templates are used in your project.
