# Elements

_The following elements are available in my Homepage._

## Regular Markdown

Tba.

## Rich Markdown

### General

Rich Markdown is Markdown with known heading markers.

A marker is a readable tag in square brackets.

```md [] Markdown: Marked heading
## My life [timeline]
```

Only known markers are transformed.
Unknown bracket text stays normal Markdown.

A marked section uses Markdown hierarchy
* The marked heading starts the section.
* The next heading of the same or higher level ends it.
* Direct child headings are mechanism entries.
* Mechanisms may interpret list structure as data.

### Timeline

`[timeline]` turns a marked section into a timeline.

#### Legend

Legend groups come before timeline entries.
A legend group is a paragraph followed by switch list items.
A switch list item uses this shape:

```md [] Markdown: Timeline switch
- Display label [Field key:false]
```

The field key maps the switch to timeline fields.
The boolean sets the default switch state.

#### Filtering

Switches control fields by key.
Inactive switches hide matching fields.
Empty field groups are hidden.
Entry body Markdown is always visible.

#### Entries

Direct child headings are timeline entries.
The entry heading text is the timestamp.
Entry order follows document order.

Consecutive `Key: Value` list items form one field group.
A blank line starts a new field group.

Other entry content stays Markdown.

## Elements in Tutorials

[Tutorials](https://homepage.sefzig-net.workers.dev/tutorials) use the same shared Element pipeline and renderer as Blog Posts. Notes, code, media, Lists, Listings, tooltips, embeds, personalization, and future shared Elements retain their ordinary behavior within the selected section. Existing restrictions for content-specific features still apply.

Use a `Tutorials` Listing with the same source, filter, sort, and display options as the other Listing kinds. Navigation buttons use the [Tutorial navigation syntax](https://homepage.sefzig-net.workers.dev/docs/markdown#tutorial-navigation).
