html jquery修改height,html - JQuery: dynamic height() with window resize() - Stack Overflow

I'm having an issue identical to this poster:

Jquery problem with height() and resize()

But the solution doesn't fix my issue. I have three stacked divs, and I want to use JQuery to make the middle one adjust in height to 100% of the window height, minus the height (23px * 2) of the other top & bottom divs. It works on resize, but it's off (short) by 16px when the document initially loads.

HTML

top

help me. seriously.

bottom

CSS

html,

body {

width:100%;

height:100%;

}

.bg {

width:315px;

height:23px;

margin:0 auto;

text-indent:-9000px;

}

#bg1 {background:url(../images/bg1.png) 0 50% no-repeat;}

#bg2 {background:url(../images/bg2.png) 0 50% no-repeat;}

#content {

width:450px;

margin:0 auto;

text-align: center;

}

JQuery

$(document).ready(function(){

resizeContent();

$(window).resize(function() {

resizeContent();

});

});

function resizeContent() {

$height = $(window).height() - 46;

$('body div#content').height($height);

}
