SlideUp in IE7 quirks mode flickers

Reported by: Siderite Owned by:
Priority: major Milestone: 1.4
Component: effects Version: 1.3.2
Keywords: slide ie7 quirks flicker Cc:
Blocked by: Blocking:

The slideUp effect animates an element from its height to 0px then hides it. Because of a quirks mode rendering issue, when setting height to 0px the div briefly returns to the original size creating a flicker.

The solution I found: replace target.slideUp(speed,callBack) with

var h = target.height();


{ height: '1px' },


function() {






I think this can be implemented directly in the jQuery engine with no side effects.

Or you can just made sure that your document isn't in quirksmode (provide a proper doctype) - which is what we typically recommend when encountering this issue.

I just wanted to comment on this. I am still having this issue using jQuery 1.6.1, and I am creating sites on an intranet, without access to the Internet. I tried changing the doctype, but that did not remedy the problem for me. However overriding the jQuery hide to use a height of 1 rather than 0, as suggested on Siderite's blog, works for me on IE7, IE8, and FF4. Why wouldn't this change get into jQuery?
