Header
======

Base class: :doc:`Fragment`

`Header` is a special fragment that automatically calculates its level.
This means that you will get `h1` for the top level, `h2` for the next level,
and so on. If you want a specific `h1`/`h2`/etc tag use `Fragment`.

The header level is only increased by the existence of `Header` objects,
so putting a manual `h1` somewhere won't make the next `Header` into a
`h2` tag.
