Dan Gookin has posted a fun (and free!) pdf that should be useful to any blogger unfamiliar with basic html.
Dan says “It was a fun project. Despite there being only a handful of truly useful or fun HTML text formatting commands, the thing ended up being 26 pages long. But it’s 26 fun pages. I even got a chance to recycle some artwork from my old and never completed Web Publishing book (from 2002). So I hope folks enjoy it and can get a lot from it.”
