I'm increasing the width of a div using jQuery's .animate().
The div contains a child element which is absolutely positioned, with its boundaries crossing the parent's boundaries.
When the animation starts, the part of the child's div outside the parent element becomes invisible, when the animation is finished, it's visible again.
<div id=parent>
<div id=child>
</div>
</div>
#parent{
width: 200px;
height: 200px;
background: blue;
position: relative;
overflow: visible;
}
#child{
width:100px;
height: 10px;
background: red;
position: absolute;
right: -50px;
top: 100px;
}
$("#parent").animate({width: '300'}, 2000);
LIVE DEMO
jQuery animate automatically forces the element to overflow:hidden; while it's animating.
You can fix this with an !important CSS Style:
#parent{
width: 200px;
height: 200px;
background: blue;
position: relative;
overflow: visible !important;
}
Edit
Due to CSS precedence, inline styles may override !important styles. If so, try something like this
$("#parent").animate({width: '300'}, 2000).css('overflow', 'visible', 'important');

I am trying to overlay 2 DIV's in my main parent DIV:
I want to overlay the the second div over on top of the first one. I have a problem overlaying it as I cannot keep it in the middle of the screen.
I have tried this to overlay:
The overlay works fine here, but my container is no longer center when I do this. How can I overlay and keep it center ?
div {
border: 5px solid red;
}
#first {
position: absolute;
z-index: 1;
border-color: orange;
}
#second {
position: absolute;
z-index: 2;
border-color: green;
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
Here is what you need to do (see width of both divs and text-align properties):
You can give them background color to see z-index works perfectly :)
#first {
text-align: center;
height: 300px;
width: 100%;
position: absolute;
z-index: 1;
}
#second {
text-align: center;
height: 300px;
width: 100%;
position: absolute;
z-index: 2;
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
When you position absolute, the positioned element is taken out of the document flow and positioned relative to the next highest parent element that is not the default position, i.e. not position: static;
The following will cause the absolute positioned children to stay within the containing div:
#container {
position: relative;
}
Your container's text is no longer centered because you have removed its children from the document flow. In essence, it has no content and collapses, and therefore, has no width to which to align the text.
One thing you could do is set the container to position: relative and full-width (i.e. width: 100vw), then set its children to width: 100%.
Then the inner divs will take on the width of their parent.
See this working JSFiddle.
#container {
position: relative;
width: 100%;
height: 100px;
background-color: yellow;
display: flex;
justify-content: center;
align-items: center;
}
#first{
position: absolute;
}
#second{
position: absolute;
}
<div id="container" class="container">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
Your main issue is that the divs will not have any relative width to the parent div.
Therefore the text is still technically "centered" in each corresponding div because they're inheriting text-align: center from the container div.
However, the divs' widths will automatically be as wide as they needs to be (i.e. to fit the text, in this case).
You can remedy this one of two ways:
Force the divs to be centered
Give both divs the following (extra) CSS:
left: 50%;
width: 100%;
margin-left: -50%;
This will literally center them in their parent div.
or
Force the divs to be the same size as their parent
Give both the divs the following (extra) CSS:
top: 0;
bottom: 0;
left: 0;
right: 0;
This sets the divs to span their entire parent's height and width.
In both situations, you might need to make the .container class use position: relative, in order for the child divs to have something to be absolute to.
If you're using Bootstrap, there is no need to worry about this, as .container class already has this applied.
Hope one of these solutions helps you :)
Try this style:
#first,
#second {
left: 50%;
transform: translate(-50%, 0);
}
div {
border: 5px solid red;
}
#first {
position: absolute;
z-index: 1;
border-color: orange;
}
#second {
position: absolute;
z-index: 2;
border-color: green;
}
#first,
#second {
left: 50%;
transform: translate(-50%, 0);
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
I am working on a form that has multiple pages that I would like to scroll in/out of view. I have to use absolute positioning to force the divs (pages) to scroll in a single line; however, this causes the parent divs height to not be responsive to the children (which have varying heights based on amount of content plus dynamic content being added to them).
How can I make the parents height be responsive to the children while still allowing my pages to scroll in a single line (I have already tried float)?
Is there anyway to achieve the same effect as the jsFiddle Demo without having to use absolute positioning?
Example: jsFiddle Demo <--- How do I make the toggle button remain below the divs no matter how tall they are?
#div1{
width: 500px;
height: 110px;
background-color: blue;
position: absolute;
top: 0px;
left: 0px;
}
#div2{
width: 500px;
height: 110px;
background-color: red;
position: absolute;
top: 0px;
left: 0px;
}
.container {
width: 800px;
position: relative;
height: 100px;
}
<p>some content here </p>
<div class="container">
<div id="div1"></div>
<div id="div2"></div>
</div>
<button>Toggle</button>
EDIT
Updated jsFiddle to show problem better.
You inspect the height and position of the child elements and calculate the total height and apply that to the parent. Absolutely-positioned elements have their own layout context, so CSS alone cannot solve this.
The height in #div1 and #div2 is causing an overflow of the .container div:
Set the height of #div1 and #div2 to the same height as its container:
#div1{
width: 500px;
height: 100px;
background-color: blue;
position: absolute;
top: 0px;
left: 0px;
}
#div2{
width: 500px;
height: 100px;
background-color: red;
position: absolute;
top: 0px;
left: 0px;
}
Or set the .container to overflow:hidden:
.container {
width: 800px;
position: relative;
overflow:hidden
height: 100px;
}

Depending on what you want, i Updated your fiddle:
Button position is fixed at document loading, based on height of the biggest absolute element:
$(function(){
$('#container').height(Math.max($('#div1').height(),$('#div2').height()));
});
you can see the fiddle here
Button position is recomputed each time the toggle is done, you can use the complete option of one of your toggle to handle it:
$div2.toggle('slide', {
direction: 'left',
complete:function(){
$('#container').height($('#'+currentDiv).height());
}
}, 'slow');
see the fiddle here
use min-height for #div2
#div2{
width: 500px;
min-height: 100px;
background-color: red;
position: absolute;
top: 0px;
left: 0px;
}
Imagine an HTML page like the following one:
<body>
<div class="main">
<div class="free">aaa</div>
</div>
</body>
The free div is absolutely positioned, and its position is outside the visible area of the browser. Because of that, it will generate an overflow, and scrollbars will be shown. This is ok.
The main div, instead, should be as big as the full area inside the browser. It shouldn't be limited to the visible area.
html, body {
height: 100%
}
.main {
background-color: gray;
width: 100%;
height: 100%;
}
.free {
position: absolute;
width: 100px;
height: 100px;
left: 3000px;
top: 3000px;
}
As you can see here, http://jsfiddle.net/y79NS/12/, the gray div doesn't extend in the "overflow zone". It works if I add a static width/height to html and body elements, but I don't know in advance how much it should be big.
Is there a pure CSS solution? If not, what's the best way to do it with Javascript, keeping in mind that the user could resize the browser in any moment?
You are just missing a semi-colon in your CSS, also use negative margins if you want to hide .free:
html, body {
height: 100%;
}
body {
position: relative;
}
.main {
background-color: gray;
height: 100%;
width: 100%;
}
.free {
position: absolute;
width: 100px;
height: 100px;
left: -3000px;
top: -3000px;
}

I am trying to make a light box style Jquery function. Unfortunately, the .container div that contains the image div (.lightboxbackground) I want to make pop out and enlarge has position:absolute and z-index: 10 so my pop up box and background fader only take up the width and height of that parent (.container) div eg:
Would anyone know a way around this so that my .lightboxbackground and .lightbox divs can cover the whole screen?
<div class='container'>
<div class='lightboxbackground'>
<div class='lightbox'>
<img src='image.jpg'/>
</div>
</div>
</div>
.container {
position: absolute;
z-index:10;
width: 200px;
height: 200px;
}
.lightboxbackground {
background-color:#000;
opacity: 0.9;
width: 100%;
height: 100%;
position:absolute;
z-index: 11;
}
.lightbox {
width: 500px;
height: 500px;
position:absolute;
z-index: 12;
}
if you want to cover the whole screen:
.lightboxbackground {
background-color:#000;
opacity: 0.9;
width: 100%;
height: 100%;
position:fixed;
left:0;
top:0;
z-index: 11; //I would advise to change this to z-index:1000 (Note: .lightbox must also adjust to this)
}

.container is their "frame of reference", so to speak. 100% width and height of the descendants of .container means 200px for them.
Also, there is a way to attain 100% height. One of them is to to explicitly define height on html and body so you can have this reference.
And so:
Place .container as a child of body
<body>
<div class="container">...
Remove .container's width and height
Add the following style:
html, body, .container {height:100%};

click for blue div
how can i it make?
If I understand correctly, you're asking how to make the yellow div appear up beside the blue one, as you have it in the third mockup? If that's the case, then:
You'll want to read up on CSS Positioning. In a nutshell, to make the yellow div sit over everything like that, it needs to take position: absolute; It'll be positioned in relation to it's nearest ancestor that has positioning, so set #ONE to position: relative;
So:
#ONE {
position: relative;
}
#THREE {
position: absolute;
left: 100%;
top: 25%;
}
This will make the top-left of #THREE shift to the far right of and a quarter of the way down #ONE. The absolute positioning also takes it out of the flow of the document, allowing it to overlap other elements.
If you want to position elements on top of each other, use position: relative or absolute. If you want it to stick to a position on your window regardless of if you scroll, use fixed.
After defining the position, you can define top, right, bottom and left to position it where you want. To simulate the 3rd image in your example, you could add:
position:relative;
top: -220px;
left:50px;
to your #THREE elements CSS, like here:
