<SUBHEADER> tag inserts a subheader. You should use the
<HEADER> tag to break entries up into logical sections, and the
<SUBHEADER> tag to break up those sections further.
Syntax and Usage
<SUBHEADER> tag acts like the paragraph tag
<P> in that it denotes a paragraph of text that forms a subheader. In other words treat
<SUBHEADER> tags like specialised
<P> tags and do not nest
<SUBHEADER> blocks inside paragraphs.
