I like this, but yeah, seems like it fails the tests.

Some of the styling of docblock will no longer apply to the docblock-short lines since they change class. Does it matter? I think this one is needed, and maybe more?

.docblock {
    margin-left: 24px;
}

@steveklabnik I've fixed test failure, and rebased. r?

[steveklabnik]

@liigo did you check on what @bluss was saying? I'm not sure if it matters or not.

[liigo]

@steveklabnik @bluss
I think, .docblock { margin-left: 24px; } is used for making room for the [−] button at the top-left corner of a docblock.

If remove it, something will get messed:

But for docblock-shorts, there're no [-] button before them, so no need for extra margin.

[bluss]

@liigo Aha, I tested locally and that seems right. Looks like .docblock code { } is missing though, so that rule needs to be updated.

[liigo]

I'll recheck. Thank you @bluss !

[liigo]

Done. Could you have another review? Thank you! @bluss
