Titles in documentation should use the “Title” element type. There are 3 levels of definable titles, as follows.
Title elements should used to create all titles, using the HTML Heading Size on the Design tab to set the title level.
Section Titles should have a margin top of 0 to make them align with the left section line. The header that comes in a section already has this applied.
No other modifications should be required, except possibly margin top to push the title away from the content above.
