Note 03 · Structure
Let headings explain the shape of a page
A useful heading tells a reader what question the next section answers. It also gives the page a structure that works beyond its visual appearance.
Choose the question first
Imagine a reader opening the page halfway through a search. A heading such as Choosing a readable line length gives them a useful promise. A label such as More information asks them to read the whole section before learning whether it matters. Draft headings from the questions readers are likely to bring.
Keep a clear order
Use one main heading for the subject and a consistent level for its major sections. A subsection belongs inside the section it develops. Choose these levels for their relationship, then use the style sheet to adjust appearance. Making text look large does not give it the structure of a heading.
Read the outline on its own
Scan only the headings before publishing. They should form a short route through the subject without requiring the paragraphs between them. If two headings make the same promise, combine the sections or name the distinction more precisely. This check is quick enough to repeat whenever a page grows.
