I can't touch any old posts using my CSS code, and I can't make any new ones with it, because when I save the post anything like <div id="poem"> is reduced to <div>. It's probably a coincidence that this problem occurred about a day after I renewed my custom design upgrade. Old posts still show the features -- as long as I don't touch them. I re-saved one after an edit and the divs are messed up.
The blog I need help with is poetseye.wordpress.com.
