IE8 css 'bottom' returning incorrect value

[[email protected]…]

$(...).css('bottom') will return the correct css attribute percent in Chrome and pixel offset in Firefox. However, in IE8 it returns a completely unrelated value. When that same value is passed back in via $(...).css('bottom', x); The attribute is changed, which as the result of the query, should not.

$(...)[0].style.bottom returns the equivalent same value as $(...).css('bottom') in Fx and Chrome, in IE the $(...)[0].style.bottom will return the correct value, where the alternative returns something completely, from all the poking I did, unrelated.

I'm really not sure jquery wants to fix this. I've tried a four or five different messages now, but they're all flagged as spam. I don't even get a captcha to prove I'm no robot. I've even tried just the jsFiddle link.

... I replied. What gives trac-o-bot? Is it because I posted the original ticket before I had a user account?

Yes, that's what happened.

Confirmed in IE8. It returns just a few pixels.

Webkit returns percent, while Firefox/IE9/Opera returns pixels.

By the way, I've been working on getting webkit to return pixels: ​https://bugs.webkit.org/show_bug.cgi?id=29084 no idea about IE8's problem though.

This is actually a bug in "Dean Edwards Awesome Hack". Not sure if I can get IE8 to return the correct pixel value, but I can get it to return the right percent value, as IE8's currentStyle natively returns percentages like webkit.

Fix #11311. Percents not pixels for top/left/bottom/right. Closes gh-793.
