FBML sounds great, but sometimes I just want to use good ole HTML. What can I get past the parser?
There’s actually quite a lot of standard HTML you can use inside an FBML page. Keep an eye on the Wiki for an up-to-date list (http://wiki.developers.facebook.com/index.php/FBML), but this should give you a good idea:
You’ll note that
body aren’t included as valid tags,
because you shouldn’t include them in Canvas pages. This may go
against everything you know when it comes to building valid HTML
pages, but you’ll actually get an error if you include them.
