Scrolling fixed header displays farther down then desired

I am having some difficulties with a scrolling fixed header I am creating. I found a good example of it on here and now I am trying to make it work with my changes to it and I am trying to adapt it.
I put additional divs than what were in the example and now whenever I scroll past the yellow bar, the red bar(my header) displays way lower than I want.
I created a fiddle to show what it is doing.

This worked until I added my top margin to my div id join_login. It now is that far away from the top.
#join_login {
position: absolute;
right: 15%;
top: 27px;
font-size: 1em;
color: #383838;
}
How can I get this header to stay fixed at the top after I get to my scroll point?

Is this what you want? https://jsfiddle.net/zoue6gv7/1/
I just removed the margin-top -50px and replaced it with
top: 0;

This should do the trick! You can just eliminate the space above #logo by adding margin-top: -15px
#logo {
position: absolute;
left: 15%;
top: 22px;
font-size: 2em;
margin-top: -15px;
}

Just kidding! I think I misunderstood what you're trying to do, if you want the red Header to stick to the top of the page even when you scroll down:
Use position: fixed; to tell the header to stay in the same location regardless of scrolling
Use top: 0px; to tell the header, that the location you'd like it to be fixed to is the very top of the page
header {
position: fixed;
top: 0px;
width: 100%;
height: 75px;
background: red;
z-index: 100;
border-bottom: 1px solid #888888;
}

Problems with position:fixed and responsive / adaptive Layout

First look at this website: http://irismediainfo2.lili.de/spip.php?article4924
On my screen it looks like on this screenshot: chrome - full window - desktop resolution: 1440x900
I think for most of you it will look diferent but thats part of the problem...
The main div with the gray border is inside an other div with id="page".
#page {
width: 560px;
margin: 50px auto 0px auto;
position:relative;
}
I created a new div with id="toolbar", that looks like it sticks to this #page-div, but it does not scroll with the page. On the website I linked above u can see the #toolbar as a dummy-box (grey with some Text).
At the moment the I use position:fixed in #toolbar.
When I position it at the side of #page so that it LOOKS like it is attached to it, and I resize the browser window... the two divs dont move the same way because the position of #page is calculated from the middle (by margin:auto) and the position of #toolbar is calculated from the side of the browser window (by position:fixed). So it is not attatched anymore in any other windowsizes.
I tried to make the #page float, to make the #toolbar appear at the side but that destroys the "margin:auto" of the #page so it is not centered anymore.
I also tried
#toolbar {
position: fixed;
center: 0px; }
Because I hoped there could be a way to calculate the position for position:fixed from the center.
Nothing worked, I hope you know a solution.
Actually everything I want is something like:
#page {
width: 560px;
margin: 50px auto 0px auto;
position:relative; }
#toolbar {
position: fixed;
center: 0px 280px 0px 0px; }
I would like to do this with minimal code and resources because I don't want to make the loading speed worse because of a little toolbar.
If you need more specific code from my css or html please tell me.
I hope the target and the problem is clear.

All you need is a wrapper-div that centers the whole block and algin the toolbar after that, since your #page has a fixed width in every viewport.
HTML:
<div class="wrapper">
<div id="toolbar">
content
</div>
</div>
CSS:
#toolbar {
height: auto;
padding: 10px 20px 10px 15px;
background-color: rgba(170, 170, 170, 0.5);
border: 1px solid #AAA;
border-radius: 0px 5px 5px 0px;
text-align: center;
margin: 0px auto 0px 279px;
}
.wrapper {
position: fixed;
top: 30%;
left: 50%;
}

Slide animation of left floating element vs right floating element

I've ran into a inconsistency with the sliding animation in jQuery and I'm not too sure how I can overcome it.
I basically have two floating divs that act as opening and closing doors:
.door-one{
float: left;
width: 50%;
height: 100%;
background-image: url('dark-wood.png');
box-shadow: inset 0 0 10px black;
}
.door-two{
float: right;
width: 50%;
height: 100%;
background-image: url('dark-wood.png');
box-shadow: inset 0 0 10px black;
}
And the animation to govern their movements:
$(document).ready(function(){
$('.home-button').click(function(){
$('.door-one').animate({width: 'toggle'}, 1000);
$('.door-two').animate({width: 'toggle'}, 1000);
});
});
The problem exists with the left floating element. You see, the right one moves off the page to the right (images and all) in one smooth motion. The left one however just gets 'covered' up and doesn't actually 'slide' off of the page.
Is anyone familiar with this? Is there anyway to get the left element to slide off the page properly?

The background image for right door works, because the float causes it to move right as the door's width shrinks. The background image simply goes along for the ride.
The background image for the left door does not work, because the door doesn't move left when its width shrinks.
An alternative would be to animate the left door's position rather than its width.
You can do this by removing float: left and adding absolute positioning for the left door. I don't think you can toggle left for this purpose. But you can animate it in one direction or the other based on its current offset.
Snippet:
$('.home-button').click(function(){
var d1= $('.door-one');
if(d1.offset().left < 0) {
d1.animate({left: '0'}, 1000);
}
else {
d1.animate({left: '-50%'}, 1000);
}
$('.door-two').animate({width: 'toggle'}, 1000);
});
html,body {
width: 100%;
height: 100%;
margin: 0px;
}
.door-one{
position: absolute;
width: 50%;
height: 100%;
background-image: url("http://www.iconsdb.com/icons/preview/royal-blue/stackoverflow-4-xxl.png");
box-shadow: inset 0 0 10px black;
}
.door-two{
float: right;
width: 50%;
height: 100%;
background-image: url("http://www.iconsdb.com/icons/preview/royal-blue/stackoverflow-4-xxl.png");
box-shadow: inset 0 0 10px black;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

How do I get this DIV which has fixed position set by Javascript to stay within the containing DIV?

I have made a JSFiddle where I am trying to make a DIV stay fixed vertically in the viewport as the user scrolls, but stay under a header.
However, the fixed DIV, with the green border, pops over to the right edge of the viewport when you scroll down to the point where the Javascript kicks in.
How do I constrain the green DIV so that it stays within the red bordered containing DIV? Ideally its horizontal position would stay fixed relative to the right edge of the container.
CSS:
header {
width: 100%;
height: 10em;
border: purple thin solid;
}
#container {
border: thin solid red;
position: relative;
height: 100%;
max-width:30em;
margin: 0 auto 0 auto;
}
#staticRight {
border: green thin solid;
display: inline-block;
float: right;
right: 0;
margin: 2em 0 0 0;
width: 120px;
height:600px;
font-size: .82em;
line-height:2em;
}
article {
border: blue thin solid;
max-width: 20em;
}
Javascript:
var elementPosition = $('#staticRight').offset();
$(window).scroll(function () {
if ($(window).scrollTop() > elementPosition.top) {
$('#staticRight').css('position', 'fixed').css('top', '0');
} else {
$('#staticRight').css('position', 'static');
}
});

Try this code. Giving right also to your staticRight div
$('#staticRight').css('position', 'fixed').css('top', '0').css('right','20px');
Instead
$('#staticRight').css('position', 'fixed').css('top', '0');
DEMO

When you set an element to fixed, it gets out of the flow and hence setting the parent to relative would'nt matter. The fixed div gets positioned at the desired coordinates relative to the browser window. So if you can calculate the left poition from the browser, just add it to your $(window).scroll when you change it to fixed. Your code should look like this-
<div id="staticRight" style="position: fixed; top: 0px; left: 70%;"></div>

2 Minute question - HTML / CSS If div within div expands expand parent div

I have a setup lets say like follows:
<div id="nav">
<div id="innernav">
//With dynamic content here.
</div>
</div>
I am running a script that sizes #nav to the size of the browser window in height. But sometimes my dynamic content is now getting bigger than the height of the window.. Is there a way I can enforce that when #innernav exceeds #nav that #nav will increase in size?
Seen as someone asked for the script:
function resizeWindow(){var a=getWindowHeight();document.getElementById("content").style.height=(a-0)+"px";document.getElementById("nav").style.height=(a-0)+"px";document.getElementById("contentPanel").style.height=(a-10)+"px"}function getWindowHeight(){var a=0;if(typeof(window.innerHeight)=="number"){a=window.innerHeight}else{if(document.documentElement&&document.documentElement.clientHeight){a=document.documentElement.clientHeight}else{if(document.body&&document.body.clientHeight){a=document.body.clientHeight}}}return a};
Changed the script to refer to min-height works perfectly in FireFox. But not IE or Chrome.
CSS:
body {
margin: 0px;
text-align: left;
font-family: Verdana;
font-size: 11px;
background-color: #FFFFFF;
min-width: 980px;
min-height: 10px;
background-image: url('../Images/watermark.png');
background-position: 100% 100%;
background-repeat: no-repeat;
}
.nav {
width: 19%;
margin: 0px 0px 0px 0px;
background-color: #E0EFFF;
float: left;
vertical-align: bottom;
position: relative;
}
some minor changes to my script / using min height seems to work. And after running a CCLEAN IE sort of does what I wanted.

Instead of setting the "height", set the "min-height".

short solution is give height auto to both divs
