Menu
I'm working on a HTML framework that most of it's pages constructed from two section. first section (TopPanel) is a sliding panel that could slide down or up (with jQuery as well). second section is the Main part of page that could contain any sort of HTML document.
<!doctype html>
<html>
<head>
<!--Meta scripts & more-->
</head>
<body>
<div class="TopPanel">
<!--Panel's Contents-->
</div>
<div class="Main">
<!--Some standard HTML docs here-->
</div>
</body>
</html>
When the TopPanel is sliding down, all elements of the Main section must move down. But it's possible to exist some position:fixed element in the Main section. so it's clear that they won't move unless we gave them some margin-top: [$('.TopPanel').height()] px;. But it's not what I'm looking after!
I'm looking for a way to shift down and shift up all content of the Main section with a smooth effect and without changing of all elements attributes.

Have you thought about using a CSS transform:translateY(20px) on the body tag? If you are using fixed position on the other element, it shouldn't actually affect it although I haven't tested that.
You can then use transitions to get the smooth movement you are after.
body{
padding:10px;
overflow:hidden;
background:#fff;
height:100%;
transition:all .2s;
}
body.active{
transform: translateY(60px);
}

Lookout for this kind of stuff though : Positions fixed doesn't work when using -webkit-transform

(UPDATED) Try this:
$('.main').click(function(){
$('.main').toggleClass('toggle');
}).main{
width:20%;
height: 10%;
background-color: rgba(100,100,100,0.7);
text-align: center;
position: fixed;
top: 12%;
transition:all 1.0s
}
.top{
width: 20%;
height: 10%;
text-align: center;
background-color: rgba(300,50,50,0.7);
position: absolute;
}
.toggle{
transform: translateY(100px);
transition:all 1.0s
}<div class="content">
<div class="top">
Top
</div>
<div class="main">
Main
</div>
</div>It would need some tweaking but it still does what you are looking for.
