Add class to wrapper depending on status

[vpratfr]

Would be nice to toggle a class on the wrapper element when the status changes.

Currently you only do that on the content element.

This would allow to style some things on the toggle easily (for example an arrow indicator which would flip based on the wrapper class)

#27 could help in doing that manually and easily if you don't want to add that class
