# Headings and paragraphs

Headings and paragraphs are light bits of their own: `[.h]` for a heading,
`[.p]` for a paragraph. Each one has its own ID, so an answer can cite a
single paragraph and a reader can jump to a single heading.

```bitmark
[.h]
[%4]
[#Rated values]

[.p]
The rated values are given in (+bold)Table 1(-bold).

[.h]
[%4.1]
[##Ratings for type B]

[.p]
[@id: p-4-1-1 ]
Type B is rated at 20 A and 32 A.
```

## Heading levels

The number of `#` in the title sets the level, from `[#…]` (level 1) to
`[#######…]` (level 7). A heading has no body and no footer.

## Numbers and labels

`[%…]` is the item: the number or label the original gives the heading,
such as `4.1` or `Annex A`. The heading must read well without it.

## Paragraphs

A paragraph bit holds formatted text, with everything
[Text formatting](https://docs.bitmark-association.org/concepts/text-formatting.md) describes, and a small set of
tags. Use `[.p]` for each paragraph of running text; longer pieces that
belong together can stay one `[.article]`.

## Instead of titles inside a bit

Earlier bitmark wrote titles inside a bit's text (`# Title`). Write each
heading as an `[.h]` bit instead: it gets an ID, appears in a table of
contents and can be linked and cited on its own.
