It will still block the downloading of any non data uri images, so it won't feel quite as fast as the loose version, but it should still give you the progressive page rendering. And it will validate. I may do some tests on this on later... Let me know if it works for you. @Erik

I like the perceived speed, but having invalid HTML is (at least in my case) not acceptable. Invalid CSS is another case, but HTML...I still love the idea (and it was only after I implemented it that I figured out it doesn't validate - feels like a loss to merge it back into the head).. @Rob

I think when experimenting with newer web technologies we're occasionally going to rub the validator the wrong way. =) I'm not recommending that people start putting stylesheets in the footer, but I thought it was very interesting that doing so had a major (and in some ways, positive) effect on how most of the browsers rendered the page. For my two cents on validation in general, I think the <em>principles</em> of validation are very important. But I'm not sure it's important that every page validates. @Erik

Any solution to that? I agree that it improves perceived performance, but not having it validate seems a big deal...or am I mistaken?
