I'm facing problem using z-index for relative and absolute position properties, below orcitMultiselectTreeviewDropdownInner is child div of orcitMultiselectTreeviewDropdown. z-index is working as expected but I have scroll bar on the page when I scroll horizontal orcitMultiselectTreeviewDropdownInner div also change the position. How can I keep position where it should be normally even using horizontal or vertical scroll?
CSS:
.orcitMultiselectTreeviewPosition .orcitMultiselectTreeviewDropdown .orcitMultiselectTreeviewDropdownInner {
position: relative;
z-index:999999;
}
.orcitMultiselectTreeviewPosition .orcitMultiselectTreeviewDropdown {
position:absolute;
}
1) If you want to position elements on top of each other using z-index, all parent elements of the child element that has a defined z-index, must also have defined z-indexes. Z-indexing positions things "on top of each other," as you seem to know, but it only works on child-parent interactions. (Doesn't matter if child or parent div is the one "in front" or "behind")
2) Try position:absolute; for both OR try positioning .orcitMultiselectTreeviewDropdownInner with left:0; top:0; or something
3) Try z-index:999; for one and z-index:99 for the other

Goal
I would like to position an element absolutely.
Issues
Oddly, said element somehow appears as if it were position: fixed. Weird!
html, body {
height:100%;
}
.absolute {
position:absolute;
}
This creates an element that acts like it is fixed on the page.
This is very puzzling and inconvenient. Here is a JSfiddle.
Help
Is there a way that I can add absolute positioning to this element without changing html and body height?
One last thing to note: In my case, the content inside the body overflows window height, if that's important...
Thank you for your help!
edit: Changed title slightly, removed unneeded interjections.
First let's understand how position:absolute works.
absolute position removes an element from the normal flow of the document and places it relative to the first parent that has relative positioning.
The default value of position property is static. So the class .absolute has no parent that is relatively positioned. Therefore it stays relative to the viewport and appears all the time even when you scroll.
So set a parent element of .absolute to relative positioning and you will get the desired result. Here, you can set the .element to relative positioning.
.element{
width:100%;
height:2000px;
position:relative;
}
You can open the fiddle below and scroll to see the desired effect.
Fiddle - jsFiddle
by default position absolute is relative to the body beacause the absolute element is out of the elements flow. So if you want your absolute element to be abble "to understand" the other elements and be abble to move width parent, it's parent should be in relative position.
regardless to your JSFiddle put a position relative to .element the .baby should be abble to move with it parent
.element {
width:100%;
height:2000px;
position:relative;
}
I have one div - the #container - that stretches across the window, filled with a graphic. I need a bar to float over the container div on the right side. If I use position:absolute and right:0, the div is positioned according to the window, not the #container div.
If I use position:relative, then the div is positioned according to the #container div but still takes up space and won't be hovering over the #container content.
Here is a JSFiddle that I made with my attempt.
http://jsfiddle.net/y8LCu/
NOTE that I do not want to use float:right, because that would keep the side div in the flow of the content, which I do not want.
I think I got it the way you wanted it?

You needed to make the parent position: relative and if you don't want the overflow you need overflow: hidden.
position:absolute; allows you to position an element compared to any positioned ancestor.
<div class="parent">
<div class="child">
</div>
</div>
.parent { position : relative; }
.child { position : absolute; }
Now, child will position itself based on the parent.
If the parent doesn't have a position set, then it will look at the position of the grandparent...
...and on and on, and if none of them have a position set, then it will look at the position of the actual web-page.
Also, if you have multiple positioned elements (whether relative/absolute/fixed) near the same place, and you want them to overlap in an order you set in CSS, and not in the order of which is set on the page last...
...then you also need to start using z-index (which only works on positioned elements).
The higher it is, the more stuff it stacks on top of.
Set the parent's position to relative
#container
{
position:relative;
}
This is how i designed the layout for my header
<div id="DivHeader">
<div id="DivTop">
</div>
<div id="DivBottom">
</div>
</div>
Initially i had set the top property for the DivBottom as 35px.At that time i did not have DivTop. So now, after adding it, the top for the DivBottom has been calculated from the new child(DivTop) as DivTop's height + DivBottom's top. As a result the layout got collapsed like this. I need to place DivTop without affecting the DivBottom's Top, Any ideas.?
[Note : I did not use absolute positioning for my divs, Because in that case margin:0 auto wont work.]
You're using relative positioning, for which this is the expected behavior. See the W3 on relative positioning:
Once a box has been laid out according to the normal flow or floated, it may be shifted relative to this position. This is called relative positioning.
So if you insert something above a relatively positioned element, it will first position according to the "normal flow", and then be repositioned according to your CSS.
You'll need to change the position to another value if you want the behavior you specified.
You would need to use absolute positioning:
#first
{
position:absolute;
left:50%;
margin-left:-5px; /* half the width value */
width:10px;
height:10px;
background-color:yellow;
}

I have a streamed flash radio on my website and i set it to it's current position with absolute position. The problem is that with different resolutions it appears at different places. How do i fix this?
Thx!
An absolute position element is positioned relative to the first parent element that has a position other than static. Make sure the element your are absolutely positioning is not contained in an element which shifts position.
Add position:relative your #teljes :
#teljes { width: 1024px; height: 768px; margin: 0px auto; position:relative;}
Adding position:relative; to div will make all the absolute positioned children to take position according to parent div.
I am building a small web application.
I have two divs. One is absolute and the other is static.
I am trying to position my static div on top of my absolute one, so that it remains the top most item.
Very simple Code Sample:
http://jsbin.com/efuxe3/edit
How can this be done?
Edit:
I have been using z-index. It seems to have no effect.
z-index doesn't apply to static elements.
According to this page:
This property specifies the stack
level of a box whose position value is
one of absolute, fixed, or relative.
If you make your div relative instead, you can use z-index to determine the order.
position: relative positions the element relative to its default (static) position, so if you don't specify a top, bottom, left or right then there'll be no difference between static and relative other than that relative allows you to use z-index to move your element up the stack.
Edit: based on your code sample, here's a working demo.
Edit 2: based on Nathan D. Ryan's suggestion in the comments below, you could also apply a negative z-index to your absolutely-positioned div. This would move it behind everything else on the page that didn't have a lower z-index defined.
Rather than placing the statically positioned element over the absolutely positioned element, you can place the absolutely positioned element behind the statically positioned element. You can do this by setting the z-index of the absolutely positioned element to a negative value. However, as #Town mentioned, this will also place the absolutely positioned element behind everything else in the normal flow.
You can apply a negative z-index to the other elements placing them behind the static div. This can be applied directly to the other elements or you can use
*:not(connectedObjects){
z-index:-1000000000000000000000000000;
}
But this does not work in internet explorer
You could have a second absolutely positioned div to contain your statically positioned elements:
<div id="container">
<div class="underlay">
I want this to appear under my static items.
</div>
<div class="item_container">
<div class="item">blah</div>
<div class="item">yada</div>
<div class="item">foo</div>
<div class="item">bar</div>
</div>
</div>
And your css is
.underlay {
position: absolute;
z-index: 0;
}
.item_container {
position:absolute;
z-index:10;
top: 0;
left: 0;
height: 100%;
width: 100%;
}
.item {
position: static;
}
if by top you mean z-Index, you can set the style of that div with a higher z-index
div.divClassName {
z-Index:100;
}
edit:
you can change the z-index of your div, with absolute positioning to a negative, but then you will have to do so for every other element.
Unless you really have a really good reason to using positioning to static you can change it
to relative, and the z-index will have an effect.io have tried it in your code sample and it works fine;
Work with z-index attribute. The z-index of the object which should be at front must be higher than the other ones.
