Code review comment for lp:~mbp/launchpad/391780-markdown

@mbp one thing we'll need to do is style this content (for all the different types of elements Markdown generates). The consideration here is that this is a user controlled content block. We'll want to style the elements here slightly differently to how we style the same elements elsewhere (or at least have the ability to do so).

I guess to make that happen it would be easiest if the element wrapping the markdown content had the class "markdown".
