Attempt #3.
Using css, with a strict doctype, can someone please draw 4 div boxes to meet these requirements.
The wrapper or outermost div will scale in height. That means that it could be any height.
The middle div should always be 100% high to match the outer/parent div (#1 in my list)
The next div should be positioned inside, and at the top of div #2
The last div should be positioned inside, and at the bottom of div #2
NOTES:
If you use absolute positioning for this, you will put divs 3 and 4 outside of div #1 and that won't work. The key is to keep divs 3 and 4 within div #2
<div id="wrapper">
<div id="middle">
<div id="top">top</div>
<div id="bottom">bottom</div>
</div>
</div>
#wrapper { height: 200px; position: relative; }
#middle { height: 100%; }
#bottom { position: absolute; bottom: 0; }
It should work for any height you give the #wrapper.

Pseudo element not full container width when border used

As I know, child's width percentage's standard is parent's content box(only the content, without padding or margin.). So if there's a padding in parent and child's width is 100%, child's width is smaller than parents. But If I position child as a absolute and parent as a relative, child's width is just equal to the parent's no matter padding and margin in parents. Like this:
<div class="first">HI
<div class="second">
HELLO
</div>
</div>
css code
.first{
background-color: yellow;
width:100px;
height:100px;
padding:10%;
position:relative;
}
.second{
background-color: blue;
position:absolute;
width: 100%;
height:100%;
opacity:40%;
}
Eventhough parent's position and relative so Child is totally dependent on '.first'. What's the standard of child's width in this case?
This snippet shows the result of setting the second div to have position relative and then position absolute. You can see that the absolutely positioned element takes on the width of its parent including the padding.
.first {
background-color: yellow;
width: 100px;
height: 100px;
padding: 10%;
position: relative;
}
.second {
background-color: blue;
width: 100%;
height: 100%;
opacity: 40%;
}
.relative {
position: relative;
}
.absolute {
position: absolute;
}
<h2>The blue square has relative position</h2>
<div class="first">HI
<div class="second relative">
HELLO
</div>
</div>
<h2>The blue square has absolute position</h2>
<div class="first">HI
<div class="second absolute">
HELLO
</div>
</div>
The reason seems to be that:
when a box has position: absolute its containing box is the parent's padding box.
See the accepted answer to: Absolute positioning ignoring padding of parent though I am struggling to find the exact description of that in the actual standard documents and it would be good if someone could point out a primary reference.
UPDATE: thanks to Temani Afif who has pointed out this SO answer which has info. from an actual specification:
The standard of the % for position:absolute is of the nearest positioned ancestor block and if no ancestor is positioned, it is relative to body element. In your case since the first is positioned relative the second will be relative to first and if u remove the position attribute of first, second will be positioned relative to body.

When I use float, childs pop out of parents.
I just put overflow:hidden on the parent and the child pops back into its parent.
However, I can't do the same with an absolute div and a relative div.
.parent {
position: relative;
overflow: hidden;
}
.child {
position: absolute;
}
<div class="parent">
<div class="child">First</div>
<div class="child">Second</div>
</div>
The goal is to float 2 images one over another to create a slideshow, but still make the page respect the slideshow as an item.
Expected: "First" hovers above "Second" inside parent
Behavior: "First" and "second" are hidden, parent is 0px in height.
Upon removing overflow:hidden;, they appear outside the parent.
Since you have only absolute div inside a relevant parent div there is effectively no content in the parent div. You can set a preferred height to the parent div but also need to set html and body height to 100%.
Note: You would likely set your parent div to the size of your images to be displayed
I have colored the parent black and the children red for visual point of view.
Is this what you are trying to achieve? Sorry if I have miss understood your question.
html, body {
height:100%;
width:100%;
}
.parent {
position: relative;
height:50%;
width:50%;
background-color:Black;
}
.child {
position: absolute;
background-color:red;
width:20%;
height:20%;
}
<div class="parent">
<div class="child">First</div>
<div class="child">Second</div>
</div>
I need to animate my ng-view with a slide effect. Therefore I got 3 divs
<div style="overflow:hidden">
<div ng-view style="position:absolute">
<div style="position:relative"> LONG CONTENT </div>
</div>
</div>
I´m testing these effect. The outer div needs to be overflow:hidden to let my slide effekt work.The inner div needs to be absolute. If the inner div contains some text, the other 2 divs should expand the height according to the very inner div. Same like when all divs would be relative. How to achieve this?
Like in my example link but with variable height.
EDIT: This is a complete other question then the "possible" duplicate.
The problem is the size of your contents, you`re making your inner div absolute, so the parents it won’t
have any height. First thing you have to do is define size to your elements and than you can use absolute elements to make your layout.
see the example below, i define a div named .page with min-height:200px, that will be enough to appear your element (.slide), because if you don’t do this, your element(.page) height will be 0, and it will be cut by overflow:hidden.
<style>
.page {
background-color: #DDD;
overflow: hidden;
position: relative;
min-height: 200px;
}
.slider{
position: absolute;
}
.slide{
position: relative;
}
</style>
<div class="page">
<div class="slider" ng-view>
<div class="slide"> LONG CONTENT </div>
</div>
</div>
This is my app:

The container holding the widgets is a div and each widget is actually made up of a li element inside a element.
What I would like to have are 4 background columns inside the container that extend from the top of the container to the bottom and are filled in with a color. Currently, you can drag the widgets around by clicking on their header text.
I'm not sure of the best solution to add the columns. The width of each column is the width of the widget. At first, I thought maybe I could add a a div table inside the container and somehow make the element stuff just "float" on top of it. That seems kind of complex though. Another solution is to use HTML5 canvas and just draw the columns.
Any suggestions?
I would just be creating your background columns as divs with 100% height and 25% width and putting them inside a parent div that is 100% height and width, and absolutely positioned at 0,0 in your main container div. Something like:
<div id="container"> <!-- main container -->
<div>
<div></div>
<div></div>
<div></div>
<div></div>
</div>
</div>
#container > div {
position: absolute;
height: 100%;
width: 100%;
left: 0;
top: 0;
}
#container > div > div {
height: 100%;
width: 25%;
float: left;
}
I am trying to do a tableless
layout, and I have the following
HTML snippet:
<div class="slider-inner">
<div class="slider-pane">
<div class="container">
<p>...</p>
<div class="did-you-knoow">
<div class="facts">
</div>
<div class="marquee-container">
</div>
</div>
</div>
</div>
</div>
Which is styled w/ this CSS:
div.slider-pane {
width: 1024px;
}
div.container {
display: block;
}
div.facts {
margin-right: 60%;
}
div.marquee-container {
position: absolute;
top: 0;
right: 0;
margin-left: 0;
margin-right: 0;
padding: 10px;
width: 60%;
}
I want the div.facts to occupy the left-40% , and the div.marquee-container
to occupy the right-60% of the div.did-you-know (their immediate parent). I
expect the div.marquee-container to be positioned relative to its parent, and
its width to be 60% of its parent, but its positioning and width are relative
to div.slider-inner, which is 2 levels above its parent.
How do I set the position and width of div.marquee-container relative to
its parent, and not the div three levels above it?
add position:relative to div.container
#locrizak's answer is correct, I needed to add 'position:relative' to the div.container, but I needed to add it to the div.did-you-know as well. In other words, I needed to set all of the containing div's to position:relative in order for the elements in question to be positioned relative to the immediate parent.
I found this was also answered in the MDN page for css position under the 'absolute' definition:
[The browser will] position [the element] at a specified position relative to its closest positioned ancestor or to the containing block
However the W3C reference was not as helpful.
