This demonstration documents the features of
[Markdeep](http://casual-effects.com/markdeep) and acts as a test for
it. Markdeep is a text formatting syntax that extends Markdown, and a
JavaScript program for making it work in browsers. The two most
powerful features are its ability to run in any **web browser** on the
client side and the inclusion of **diagrams**.
[Click here](https://casual-effects.com/markdeep/features.md.html?noformat)
to see this document without automatic formatting.
Markdeep is free and easy to use. It doesn't need a plugin, or
Internet connection. There's nothing to install. Just start
writing in Vi, Nodepad, Zed, Emacs, Visual Studio, Atom, or another
editor! You don't have to export, compile, or otherwise process
your document.

Basic Formatting
=======================================================================================
Text formatting:
Source | Result
-----------------------------------------|------------------------------
`**bold**` | **bold**
`__bold__` | __bold__
`*italic*` | *italic*
`_italic_` | _italic_
`~~strikethrough~~` | ~~strikethrough~~
`inline code` | `inline code`
`if (inlinedHighlight == "yes") {` | if (inlinedHighlight == "yes") {
`[news](https://cbc.ca)` | [news](https://cbc.ca)
`https://casual-effects.com` | https://casual-effects.com
`morgan@casual-effects.com` | morgan@casual-effects.com
`5 kg/m^3` | 5 kg/m^3
`5 degrees` | 5 degrees
`xbelow` | xbelow
`size` | size
`size` | size
You can add CSS to change the styles. See the Custom Formatting section
for some examples.
Formatted text may **cross
lines** and be as small as **a** single character. It can _also
be indented and
split across lines_ simultaneously.
Markdeep intelligently does not apply bold or italic formatting to
math expressions such as x = 3 * y - 2 * z or WORDS_WITH_INTERNAL_UNDERSCORES.
It also protects HTML ``foo()` | `foo()`
Any section header name followed by "section", "subsection", or "sec." will automatically be
linked to that section. (The keyword "chapter" currently works but is unsupported and likely to
change to work differently with multi-file documents in the future.)
To link by number, use one of those key words followed by the section
name in brackets. This won't work if you use the actual word "section" _as the title of a
section_...but it would be unexpected to have a section named "section" in a real document
anyway.
You can also insert HTML anchor (``) tags to create arbitrary internal links.
