How do I increase the font size of the HTML Help topic heading? - On Premises 6.4

FAQs - On Premises

The styles of the topic headings in your HTML Help file are controlled by the styles for Heading 1, 2, 3, and so forth. These styles are automatically applied according to your document's topic hierarchy, with top-level topics getting Heading 1, and so on.

You can increase the size for all headings at the same level by changing the font settings on the Web tab of the Style for the relevant heading level (say, Heading 3). You cannot specify the size for an individual heading separately from the other topics at the same outline level.
