The part I'm not getting is why you need to say anything at all, since transparent is the default for all backgrounds anyway. I don't think that saying "transparent" will make the white parts of a jpg transparent, if that's what you had in mind; for that you need to set an opacity value. And then you get into MSIE support.*
FCCCDD, hm, kinda pale cream?

Oops, no, read the numbers backward. Pink? Really? Makes me think of one e-book where I wanted to use a similar background color-- it was a cookbook about desserts and sweets-- but everyone who looked at it was reminded forcibly of Pepto-Bismol. What's the theme of the site?
* I was going to say "browser support" but looked it up and it seems as if everyone else has supported opacity since the dawn of time; only MSIE <= 9 is iffy. They definitely don't like alpha channels. But that's OK, because pngs > 8bit tend to be horribly oversized and not something you'd normally want to use.
