Use header levels (H1-H6) to specify the document structure and use them as specified.
- Each page should start with H1.
- Use H2 to indicate a subsection of H1.
- H3 must not come before H2, the header levels must be used in the correct order.
- However, after H5 you can use any header level.
- Do not use header markers to create font effects.
Make sure that the headers are marked with header levels.
