Is it possible to absolutely position elements inside a fixed position container? For example:
<div style="position:fixed; left:0; top:0">
<div style="position:fixed; left:0; top:0;"></div>
<div style="position:fixed; left:200px; top:120px;"></div>
</div>
I want to be able to move, using jQuery, the container div to the left and right (and it's children along with it), but this obviously doesn't work (moving the container's left property does not affect the children).
I tried something like this:
<div style="position:fixed; left:0; top:0">
<div style="position:relative; width:100%; height:100%;">
<div style="position:fixed; left:0; top:0;"></div>
<div style="position:fixed; left:200px; top:120px;"></div>
</div>
</div>
...but it doesn't work. I know I could ultimately just drop the container and animate each of the fixed position children at the same time, but I'd really prefer not to. I'll probably end up adding more children later, and that would mean managing the animations/movements of each one (now that I think of it, I could just add a class to each child, and have jQuery animate the left property of all occurances of that class, but I'd still prefer to resolve my initial problem if possible).
Hacks are welcome!
use relative for the children, not fixed.
<div style="position:fixed; left:0; top:0">
<div style="position:relative; left:0; top:0;"></div>
<div style="position:relative; left:200px; top:120px;"></div>
</div>
The children should be position absolute (because they are positioned absolutely within the fixed container).
See this demo:
http://jsfiddle.net/74dE7/2/
#fixed-box {
position: fixed;
height: 300px;
width: 300px;
background: red;
right: 10px;
top: 10px;
}
#absolute-box {
position: absolute;
left: 10px;
bottom: 10px;
background: blue;
height: 50px;
width: 50px;
}
<div id="fixed-box">
<div id="absolute-box">
</div>
</div>

I have an interesting issue or objective here. I have an image that is a yellow rectangle with 3 red rectangles in it. I'd like to add clickable buttons as an overlay on top of the picture, right over the red rectangles.
Thing is, I would like those buttons to always be exactly over each red rectangles, same size/position, no matter the aspect ratio of the pciture, the screen resolution of the user, or the zoom percentage of his browser (as if the buttons were part of the image)
As an example, I've included a picture where the yellow rectangles and the red rectangles are part of the same image, and the dotted green line would be the overlay buttons or their respective divs.

MY HTML SO FAR
<body>
<div class="image-container">
<img src="img/justelimage.png" alt="Nature" class="video" />
<a href=“#”></a>
</div>
</body>
MY CSS SO FAR WORKS BUT THERE SHOULD BE A BETTER WAY ?
(works when I resize window, and change browser's zoom percentage, but what if we change the aspect ratio?)
.image-container {
display: inline-block;
position: relative;
margin-left: auto;
margin-right: auto;
width: 80vw;
height: auto;
z-index:0;
}
.video {
position: absolute;
width: 100%;
height: auto;
z-index:1;
}
.image-container a{
position: absolute;
margin-top:4.5%;
margin-left: 57%;
width:28.3vw;
height: 7vw;
color:white;
border: 0.25vw solid green;
z-index: 999;
}
}
Any idea how I could manage to get this in a more logical way?
Any suggestions would be gladly appreciated. Thanks!
I'd wrap the anchor in a div to center it. That way you could style
anchor separately with px while maintaining its position relative to the img.
<body>
<div class="image-container">
<img src="img/justelimage.png" alt="Nature" class="video" />
<div class="link-container">
<a href=“#”></a>
</div>
</div>
</body>
.link-container {
position: absolute;
top: 50%;
left: 50%;
}
If you also style the .image-container with a background color
and opacity you can toggle those values on :hover.
The best way to keep buttons in place with respective to an image will be to have the container as
position: relative;
and buttons inside the div as
position: absolute;
and placed top and left with px or any unit that doesn't change with size.
But one major thing you can do is have your image as the background of image-container.
That way buttons always stay on top of the image and u can restrict resizing of the container to make the buttons stay in position better.
I hope this helps.
.image-container {

At my Page there are tow sections, a header div and the contents div. I want JS or jquery solution to stick the header section at the top, so that when user scrolls the contents section would cross and cover the header section.
html:
<div id="header">
<h3>I'd like to stick here at the background, please! </h3>
</div>
<div id="content">
<h3>I'd like to cross over the header when user scrolls.</h3>
</div>
http://jsfiddle.net/KNh46/
Update: misunderstood, so you want the content to scroll over the header, not under. Then it should be like:
#header {
position: fixed;
height: 100px;
top: 0;
z-index: 100;
}
#content {
position: relative;
margin-top: 100px;
z-index: 101;
}
See an example here: http://jsfiddle.net/aorcsik/v7zav/
If your header is fixed height, say 100px, then:
#header {
position: fixed;
height: 100px;
top: 0;
}
#content {
margin-top: 100px;
}
This way when scrolled to the top, the header won't overlay the content, but when you start to scroll down, it will.
Something like this, if I understand your question:
<div id="content_wrapper" style="position:relative">
<div id="header" style="z-index:1; position:absolute; top:0px">
<h3>I'd like to stick here at the background, please! </h3>
</div>
<div id="content" style="z-index:5">
<h3>I'd like to cross over the header when user scrolls.</h3>
</div>
</div>
I'm using https://github.com/bigspotteddog/ScrollToFixed on my projects with no problems. ScrollToFixed allows you to set when the div will be fixed based on the scroll position.
fiddle with example: jsfiddle.net/ZczEt/167/
you should add css:
*{margin:0;padding:0}
#header{
position:fixed;
width:100%;
height:200px;
background:#ccc;
}
h3{
text-align:center;
}
#content{
background:#f1f1f1;
padding-top:200px;
min-height:500px;
}
jsfiddle
I myself came with another solution :
add another container div to the header and then position that div to fixed, and make the contents to be absolute. but this way you need to specify a min-height or height for the header:
http://jsfiddle.net/pna54/
<div id="header">
<div class="container">
<h3>I'd like to stick here at the background, please! </h3>
</div>
</div>
<div id="content">
<h3>I'd like to cross over the header when user scrolls.</h3>
</div>
css:
div{margin:0;padding:0}
h3{
padding:0;margin:0;
padding-top: 100px;
padding-bottom:100px;
text-align:center;
}
#header{
background:#ccc;
min-height:200px;
width:500px;
position:relative;
}
.container{
position:fixed;
width:100%;
max-width:500px;
}
#content{
background:#f1f1f1;
min-height: 500px;
position: absolute;
width:500px;
}

SOLVED:
After re-reading the w3 spec for transforms, I realised the footer was being considered part of the 3d context due to DOM structure and was being affected by rotated elements. I simply put .cardsContainer inside of another element .cards3dContainer and the footer is now not considered part of the 3d context.
-webkit-perspective:1000px; seems to state that the 3d context begins at that point in the DOM.
Having a major problem with a container that is being rotated using css3 transforms and over-writing part of a buttons hit area in another div.
The transform visually works and the container is leaning back (using rotateX). However, the button in the footer, despite being of a higher z-index and naturally stacked to be above the container, is having its hit area ignored where the rotated container and the button visually overlap. The button still 'appears' to be on top of the rotated container, but acts like it is under it.
I should mention im using Less for the css (and all the Less code does work).
I've looked through lots of similar questions and the various solutions didn't work for me. Amongst those that didn't work (vendor prefixes omitted):
translate3d(0px, 0px, 0px);
transform-style: flat;
Here is the short version of the code:
html:
<div class="screen snap" style="display: block;">
<div class="container">**<!-- has perspective set to 1000 -->**
<div class="cardsContainer"> **<!-- is rotated on x using transform -->**
<div class="card" style="left: 130px; display: block;">
<div class="cardBack"></div>
<div class="cardFront" style="opacity: 0;">
<div class="cardContent">A piece of fruit.</div>
</div>
</div>
</div>
<footer>
**<!-- at certain screen sizes, when the container and footer overlap, top half of this buttons hit area is inactive-->**
<button class="checkButton">Start</button>
</footer>
</div>
</div>
Here are the full length files, look forward to any advice / tips:

}
After re-reading the w3 spec for transforms, I realised what the problem was.
-webkit-perspective:1000px; seems to state that the 3d context begins at that point in the DOM. I was applying the perspective style to the container which both the footer and the cardsContainer were part of. The footer was then being considered part of the 3d context due to DOM structure and was being affected by rotated elements.
I simply put .cardsContainer inside of another element .cards3dContainer and the footer is now not considered part of the 3d context because it is now not inside the dom structure which has perspective style set.
The new structure is now this:
.screen.snap .container{
.cards3dContainer{
-webkit-perspective:1000px;
.cardsContainer{
}
}
.footer{
}
}
Apologies to anyone who may have been working on an answer at the moment.
I am continuously drawing some lines in my canvas using kinetic.js and I want a div-text to appear on top of this canvas. Using relative and absolute trick I can place a div in the middle of my canvas but the problem is as I am continuously drawing lines, these lines are being drawn on top of my div-texts which I dont want to happen!
Basic template:
<div id="div-text" style="background-color:#00baba; position: absolute; margin-top: 50%; margin-left: 50%;">
greatTexts
</div>
<div id="container" style="position: relative; width: 100%; height: 100%;">
<canvas></canvas>
</div>
I believe you could also just set a z-index value on both #container and #div-text.
Like this:
<div id="div-text" style="background-color:#00baba; position: absolute; margin-top: 50%; margin-left: 50%;z-index:999;">
greatTexts
</div>
<div id="container" style="position: relative; width: 100%; height: 100%;z-index:990;">
<canvas id="myCanvas" height="500" width="500"></canvas>
</div>
This shows an example.
A canvas if by default empty, meaning you can see elements behind it.
Since you placed your <div> before the <canvas>, in the code, the <div> is rendered under the <canvas>.
Solution? Switch the divs around a little:
<div>
<canvas style="position:absolute; width:100%; height:100%; background:red"></canvas>
<div id="div-text" style="background-color:#00baba; position:absolute; margin-top:50%; margin-left:50%;">
greatTexts
</div>
</div>
Just place the div with text after the container div like this
<div id="container" style="position: relative; width: 100%; height: 100%;">
<div id="div-text" style="background-color:#00baba; position: absolute; margin-top: 50%; margin-left: 50%;">
greatTexts
</div>
There's no need to create a canvas element, because as you've mentioned, KineticJS automatically creates those for you.
I want to create an Element, which is very thin, and very high. I want the element to be visible all time, even if you scroll to the right. It should be position:fixed to the right, and left, but it should be scrollable down and up.
I searched with google, but couldn't find an appropiate way to solve the problem.
I only found this site:
http://demo.rickyh.co.uk/css-position-x-and-position-y/
This is exactly, what I want to have, BUT I am using jQuery, and not MooTools. I am looking for the same function in jQuery. I do not really want to use 2 Frameworks. Does anyone know help? Anything? I have been looking several hours, but I can't find something that fit to my needs in jQuery.
Here's a solution with jquery
jsfiddle demo
the html
<div style="width:1000px;height:1000px;">
<div id="box1" class="box" style="left:20px;top:20px;">
My position-x is fixed but position-y is absolute.
</div>
<div id="box2" class="box" style="left:20px;top:120px;">
My position-x is absolute but position-y is fixed.
</div>
<div id="box3" class="box" style="left:20px;top:220px;">
Im positioned fixed on both axis.
</div>
</div>
the code
$(window).scroll(function(){
var $this = $(this);
$('#box1').css('top', 20 - $this.scrollTop());
$('#box2').css('left', 20 - $this.scrollLeft());
});
and some css
.box
{
width:400px;
height:80px;
background:gray;
position:fixed;
}
Depending on a previous answer that helped me with what I was trying to do, keeping a header div with position-y fixed, a left div with position-x fixed, and a content div which would scroll on both x and y.
Figured I would post my jsfiddle in case anyone finds it useful:
My jsfiddle demo
The HTML
<body>
<div style="width:5000px;height:1000px;">
<div id="box1" class="box">
My position-x is fixed but position-y is scrollable.
</div>
<div id="box2" class="box">
My position-y is scrollable but position-x is fixed.
</div>
<div id="box3" class="box">
My position-x and position-y are both scrollable.
</div>
</div>
The code
$(window).scroll(function(){
var $win = $(window);
$('#box2').css('top', 0 -$win.scrollTop());
$('#box1').css('left', 120 -$win.scrollLeft());
$('#box3').css('left', 120 -$win.scrollLeft());
$('#box3').css('top', 20 -$win.scrollTop());
});
The CSS
.box {
position:fixed;
}
#box1 {
top: 0px;
left: 120px;
width: 1000px;
height: 20px;
background-color: #FF0000;
z-index:150;
}
#box2 {
top: 0px;
left: 0px;
width: 120px;
height: 520px;
background-color: #00FF00;
z-index:200;
}
#box3 {
top: 20px;
left: 120px;
width: 1000px;
height: 500px;
background-color: #0000FF;
color: white;
z-index:100;
