I played around with "January" and set up a stylesheet for you to look at. I'm not sure I got rid of the inter-stanza extra line you were asking about. See the attachment.
Anyway, here is a link to an html tutorial.

P.S. I edited "January" using search and replace and changed a few things that caught my eye, so don't be surprised if you find some glaring errors. I didn't proof it.
