I want to fix position of div with respect to it's container div, NOT with respect to body. I played a lot and searched as well but didn't find the solution.
Please not .container and .content both are of responsive height and can't take a fixed height. height:2000px; given to .container for demontration purposes only.
While the actual case is: heights are responsive. Here is jsFiddle
<div class="content">content<br>content<br>content<br>content<br>content
</div>
<div class="container">content
<div class="loaderWrap">
<div class="loader2">Loading Spinner</div>
</div>
</div>
CSS:
.content {
background:green;
}
.container {
position: relative;
background:orange;
height:2000px;
}
.loaderWrap {
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
background: red
}
.loader2 {
position: fixed;
top: 50%;
left: 50%;
}

I'm curious whether it's possible with CSS to have a <div> overlaying the <div> above and below, like so:
I've tried to use margin-top: -40px;, but that doesn't seem to work. I've tried position:relative; without any luck, either. Any ideas?
Thanks!
Sure!
Demo Fiddle
The trick is managing the positioning of your divs, then setting the offset (top) correctly for the div you want overlapping.
<div></div>
<div>
<div></div>
</div>
CSS
div {
width:100%;
height:100px;
position:relative; /* ensure the parent divs have a position set */
}
div:first-child {
background:red;
}
div:last-child {
background:blue;
}
div:last-child div {
opacity:.5;
height:50px;
background:white;
position:absolute; /* position relative to the parent */
top:-25px; /* position the top to -25px (half its height) above the top of the parent */
}
There are many ways to do this:
With all div's absolutely positioned
You can use position: absolute to achieve this. This is better if you are trying to build a web app as it sticks to the edges of the screen.
Fiddle here
HTML
<div id="top-section"></div>
<div id="banner-section"></div>
<div id="btm-section"></div>
CSS
div {
position: absolute;
left: 0;
width: 100%;
}
#top-section {
top: 0;
bottom: 50%;
background: red;
}
#btm-section {
top: 50%;
bottom: 0;
background: blue;
}
#banner-section {
height: 100px;
margin-top: -50px;
top: 50%;
background: rgba(255,255,255,0.5);
z-index: 2;
}
With the #banner-section relatively positioned
You mentioned that you tried relative position. This is how you can achieve what you were trying to do. In this case, you want the #banner-section to be nested inside the #btm-section:
Fiddle here
HTML
<div id="top-section"></div>
<div id="btm-section">
<div id="banner-section"></div>
</div>
CSS
#banner-section {
position: relative;
top: -50px;
height: 100px;
background: rgba(255,255,255,0.5);
}
With a negative margin on #banner-section
You also mentioned that you tried using a negative value for the margin-top. Here is a working example of that:
Fiddle here
HTML
(Also nested)
<div id="top-section"></div>
<div id="btm-section">
<div id="banner-section"></div>
</div>
CSS
#banner-section {
margin-top: -50px;
height: 100px;
background: rgba(255,255,255,0.5);
}
You can also have it poking out of the top section
If the #top-section is static and the bottom section can extend past the bottom of the page, this might be the best option for you.
Fiddle here
HTML
<div id="top-section">
<div id="banner-section"></div>
</div>
<div id="btm-section"></div>
CSS
#banner-section {
position: absolute;
bottom: -50px;
z-index: 2;
height: 100px;
background: rgba(255,255,255,0.5);
}
Without further details you can do it as follows:
JSFiddle Example
HTML
<div class="top-section"></div>
<div class="banner-section"></div>
<div class="btm-section"></div>
CSS
.top-section{
height:60px;
background-color:red;
}
.btm-section{
height:60px;
background-color:blue;
}
.banner-section{
position:absolute;
z-index:1;
margin-top:-20px;
height:40px;
width:100%;
background-color:rgba(255,255,255,0.5);
}
End Result
The trick here is to have the middle div banner-section positioned absolutly, and with a margin-top value negative corresponding to half its height, giving us this end result:
Explanation
Since the element with the CSS class .banner-section gets positioned absolutely, it will rise above in the document stack order. So the elements .top-section and .btm-section stay one after the other.
An element with position:absolute will then need some extra css to keep up with the desirable appearence, like a width declaration and a height declaration to set its size.

<div class="outer">
<div class="topSec"></div>
<div class="midSec">Midcontent</div>
<div class="btmSec"></div>
</div>
CSS
.outer {
position: relative;
height: 400px;
text-align: center;
}
.topSec {
height: 50%;
background: red ;
}
.btmSec {
height: 50%;

}
I'm trying to create a layout with a header, a main content area and a footer.
Both header and footer are fixed height but content area needs to fill the width and height (without scrollbars)
the current code is here
<div class="outer">
<header>
movistar ovacion
</header>
<div id="content" >
<section class="step-1">
<div class="box">
HOMBRE
</div>
<div class="box">
MUJER
</div>
<div class="box">
NIÑO
</div>
<div class="box">
NIÑA
</div>
</section>
</div>
<footer>
footer
</footer>
</div>
The CSS:
html,body{
height: 100%;
}
header {
height: 160px;
background: blue;
}
#content {
}
footer {
height: 60px;
position:absolute;
width:100%;
bottom:0;
background: green;
}
.outer {
}
.step-1 > div {
width: 50%;
height: 50%;
position: absolute;
}
.step-1 > div:first-child {
background: #DDD;
left: 0;
}
.step-1 > div:nth-child(2) {
background: #CCC;
right: 0;
}
.step-1 > div:nth-child(3) {
background: #72CCA7;
left: 0;
bottom: 0;
}
.step-1 > div:nth-child(4) {
background: #10A296;
right: 0;
bottom: 0;
}
Right now the content area doesn't work as it should, the 4 boxes doesn't adapt to the height.
I think i'm doing something wrong with div positions or clearings but i can't find the problem.
How can i fix it? Is there a better way of doing this layout?
The problem is that the first and second <div> element within the .step-1 don't have an explicit top value. Hence the next absolutely positioned DIVs overlap those two:
.step-1 > div:first-child {
background: #DDD;
left: 0;
top: 0; /* Added declaration */
}
.step-1 > div:nth-child(2) {
background: #CCC;
right: 0;
top: 0; /* Added declaration */
}
On the other hand, the #content itself should be positioned absolutely in this case in order to fill the remaining space between the header and the footer:
#content {
position: absolute;
top: 160px; /* = height of the header */
bottom: 60px; /* = height of the footer */
width: 100%;
}
WORKING DEMO.
Personally, I prefer creating a new containing block for the absolutely positioned elements instead of relying to the initial containing block. Because of that, In the above demo I positioned the .outer element relatively:
.outer {
position: relative;
height: 100%;
}
Adding right: 0; seem to helped
top: 100%;
left: 0;
right: 0;
What I am trying to is have a header image centered on the top with a different color background on either side, dynamically filling the rest of the page. The structure would look like this:
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Center"></div>
<div id="Header_Right"></div>
</div>
The Header_Center is of 960px and the Header_Left and Header_Right should fill either side of the image to the edge of the page and change width as the page width changes.
I can not get the CSS to work properly.
I assume you want those 3 divs to fill each with different content, the outsides filled fluidly or multiline. Otherwise the answer could be much 1) more simple. I also assume that the center div defines the total height of the header.
Given these two assupmtions, still a few different scenarios are thinkable of which I will give 4 examples from which you can choose the best fitting solution.
The HTML is exactly yours.
The CSS looks like:
#Header_Container {
width: 100%;
position: relative;
}
#Header_Left {
position: absolute;
left: 0;
right: 50%;
margin-right: 480px;
}
#Header_Right {
position: absolute;
left: 50%;
right: 0;
margin-left: 480px;
top: 0;
}
#Header_Center {
width: 960px;
position: relative;
left: 50%;
margin-left: -480px;
}
Now, you could change behaviour of left and right with a few extra styles:
height: 100%;
overflow: hidden;
See demonstration fiddle.
1) When the sides may be partially invisible outside the browser window (in case which you would align content in de left div to the right, and vise versa), then I suggest the solution in this fiddle demo which does not require absolute positioning at all so that any content below the header is properly cleared in all circumstances.
You must fix it using padding and box model + position : relative - it can be done without HTML Change
<div id="Header_Container">
<div id="Header_Left"></div>
<div id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
And CSS ( 100px is for example )
#Header_Container{ overflow: hidden; height: 100px; }
#Header_Container *{ box-sizing: border-box; height: 100%; }
#Header_Left{ width: 50%; padding-right: 480px; }
#Header_Right{ margin-left: 50%; width: 50%; padding-left: 480px; position: relative; top: -100% };
#Header_Center{ margin: 0 auto; width: 960px; position: relative; top: -200%; }
Example is here http://jsfiddle.net/ZAALB/2/
EDITed incorrect example
If I got you right then this might be a possible solution.
#container {
width: 100%;
height: 150px;
}
#left {
position: absolute;
left: 0;
width: 50%;
height: 150px;
background-color: #FF0000;
}
#right {
position: absolute;
right: 0;
width: 50%;
height: 150px;
background-color: #0000FF;
}
#center {
position: absolute;
left: 50%;
margin-left: -480px;
width: 960px;
height: 150px;
background-color: #888888;
}
#left basically says that the element will be positioned absolute and attached to the left side with a width of 50%. Same applies to #right just for the right side.
#center positions the element absolute pushed 50% to the left and then with a negative margin of width/2 which in your case would be 480px to position it in the center.
The order of the elements in the HTML is important for this hack.
<div id="container">
<div id="left"></div>
<div id="right"></div>
<div id="center"></div>
</div>
The #center DIV must be the last element if you don't want to work with z-indexes.
Here's a fiddle to test it.
HTML:
<div id="Header_Container">
<div class="Header_Side" id="Header_Left"></div>
<div class="Header_Side" id="Header_Right"></div>
<div id="Header_Center"></div>
</div>
CSS:
#Header_Container {
position: relative;
width: 100%;
}
#Header_Container > div {
height: 158px; /* height of the image */
}
.Header_Side {
position: absolute;
width: 50%;
}
#Header_Left {
left: 0;
background-color: blue;
}
#Header_Right {
left: 50%;
background-color: green;
}
#Header_Center {
position: relative;
width: 158px; /* width of the image */
margin: 0 auto;
background-image: url('...');
}
Also see this example.
This works, but you need to change your HTML: http://jsfiddle.net/gG7r7/1/
HTML
<div id="header_background_container">
<div id="header_left"></div>
<div id="header_right"></div>
</div>
<div id="header_content_container">
<div id="header_content"><p>Content goes here</p></div>
</div>
CSS
#header_content_container {
position:absolute;
z-index:1;
width: 100%;
height: 100%;
}
#header_content {
width: 960px;
margin: 0 auto;
background: red;
height: 100%;
}
#header_left {
background: white;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
#header_right {
background: black;
width: 50%;
height: 100%;
position: absolute;
z-index: 0;
}
I want:
<div style="height:100%">
<div style="height:70px;">header</div>
<div style="overflow-y:scroll;">main</div>
<div style="height:60px;">footer, alw. at bottom parent-div</div>
</div>
The real (px) container height may change dep on client window-size,
height of footer and header set in css-theme.
All positioning should be relative. Is JS required to solve this?
(Tried height:auto on main, seem to have no effect.)
You can use absolute positioning to achieve this quite easily, why should it be positioned relative?.
#header, #main, #footer {
left: 0;
right: 0;
position: absolute;
}
#header {
top: 0;
height: 70px;
background-color: yellow;
}
#main {
top: 70px;
bottom: 60px;
background-color: lime;
overflow: auto;
}
#footer {
bottom: 0;
height: 60px;
background-color: red;
}
JSFiddle: http://jsfiddle.net/Tg8g5/
I'm working on a prototype of a website here:
http://www.paulgrantdesign.com/valcomp/index.php
I have a div in the middle that is set to stick in the middle. It's got a given height, so in the css I did
#middle {
height: 225px;
width: 100%;
background-color: #56a6c4;
position: absolute;
top: 50%;
margin-top: -112px;
z-index: 100;
}
It sits in the middle, as required. But when the window gets too small, I don't want it to cover what's above it. Can I set it so that there's always a minimum amount of distance between the top of the window and the top of this div?
May be you can use media query for this like this:
#media only screen
and (min-width : 1000px) {
#middle {
color:red;
}
}

put position:relative on the body.that s a first step. I m trying..hold on..
and bottom--position:absolute. It works! yeah!
I fixed your problem by changing your html like this:
<div id="container">
<div id="top">
<div id="topcontent">
<p id="mobile">Mobile data collection</p>
<p id="slogan">Collect. Send. That's it.</p>
</div>
</div>
<div id="middle"></div>
</div>
Then changing your css like this:
#container{
width: 100%;
position: absolute;
min-height: 350px;
bottom: 20%;
top: 0;
}
#top {
width: 825px;
min-height: 250px;
display: block;
position: absolute;
left: 50%;
height: 50%;
margin-left: -412px;
overflow: auto;
bottom: 250px;
}
#topcontent {
width: 100%;
position: absolute;
bottom: 0;
}
...
#middle {
height: 225px;
width: 100%;
background-color: #56a6c4;
position: absolute;
bottom: 0;
margin-top: -112px;
z-index: 100;
}
It might need some tweaking to get it exactly how you want it; especially with the #bottom div
You need to add the attribute z-index to the elements #top and #bottom, and let them less than the z-index of #middle.
