Demo embedding

Sometimes just pictures of the pattern you’re documenting aren’t enough. Interactive patterns benefit from live demos, so that readers can test their functionality.

## CodePen

Infusion offers a couple of ways to do this. The first is by embedding CodePen demos into the content. The `codePen` shortcode takes just one argument: the codePen’s `ID`.

    {{% codePen VpVNKW %}}

This will embed the identified codePen into the content wherever you placed the shortcode, with the result view showing by default:

The compiled site will output an error if your `config.toml` does not include your CodePen username (in the `codePenUser` parameter). This is needed to construct the embed URL.

## jsBin

You can embed JS Bins just like CodePens, supplying a single `id` parameter.

    {{% jsBin juwowaq %}}

However, you can also have finer control over which panes are displayed. Use two parameters: one for the `id` and another, `show`, listing the panes you want to include.

    {{% jsBin id="juwowaq" show="css,output" %}}

The options for the `show` parameter are:

- html
- css
- js
- console
- output

(Note that, under some circumstances, the `html` pane is added whether you select it or not.)

## Inline demos

Infusion also supports the ability to write inline demos directly in markdown files. See
