## Fragments
|
||||
|
||||
Make content appear incrementally
|
||||
|
||||
```
|
||||
{{%/* fragment */%}} One {{%/* /fragment */%}}
|
||||
{{%/* fragment */%}} **Two** {{%/* /fragment */%}}

{{%/* fragment */%}} Three {{%/* /fragment */%}}

Press `Space` to play!

||||
|
||||
{{% fragment %}} One {{% /fragment %}}

{{% fragment %}} Three {{% /fragment %}}
|
||||
|

A fragment can accept two optional parameters:
