Most browsers display all headings with a bold style. Browsers also tend to put white space both above and below a heading. Typical spacing is 12 points both above and below, but that can vary by size and browser.

By default, Terry Morse Myrmidon identifies a single line of text as a heading if it is styled in bold and has 12 points of white space above and below it. This most closely matches the way that browsers display headings. If you are converting a document whose headings don't match the default conversion settings, you can tell Terry Morse Myrmidon how to tell them apart by selecting the matching check boxes for Bold, Italic, Underline, Outline and Shadow in each of the Heading dialog boxes. But if you do change the settings, the Web page will no longer look as "WYSIWYG" (what you see is what you get).

Terry Morse Myrmidon strives to produce "what you see is what you get" conversions, so it is particular about what text gets converted to a heading style. In order to be converted to a heading, source text must:

1. have the specified minimum size and spacing,
2. match the specified text style, and
3. occupy only a single line.

You may not want to use all of the headings available in HTML. If you don't want to create a heading of a certain size, you can simply click the "Off" button for that heading level. You can also turn all headings on or off with the appropriate button. Since the browser has control over how it displays headings, you may wish to turn all of them off to make the Web page more WYSIWYG.
