By default, a DIV\'s height is determined by its contents.
But, I override that and explicitly set a height with jQuery:
$(\'div#someDiv\').height(so
to remove the height:
$('div#someDiv').css('height', ''); $('div#someDiv').css('height', null);
like John pointed out, set height to auto:
auto
$('div#someDiv').css('height', 'auto');
(checked with jQuery 1.4)
