I tried to slide in and out a DIV with the toggle function of jQuery but the result is always jumpy at the start and/or end of the animation. Here\'s the js code that I use:
I was using slideDown() like this
$('#content').hide().delay(500).slideDown(500);
For me, it was the main container #content element. I was having it hidden and then calling slideDown(). I removed the padding property in the CSS and everything worked fine after that. It's usually a margin, padding, or % width, so the easiest method is commenting out each property and testing them 1 by 1 to get your results.
