Make element 100% height of parent - html

I have a parent which has the CSS property of table-cell, with a child element that need to be 100% the height of the parent. I cannot get this to work in IE Edge - any ideas?
<div class="table">
<div class="table-row">
<div class="table-cell-1">
<a>need 100%!</a>
</div>
<div class="table-cell-2">
some content<br>
that is <br>
quite high
</div>
</div>
</div>
.table {
display:table;
}
.table-row {
display:table-row;
}
.table-cell-1, .table-cell-2 {
display:table-cell;
width:100px;
}
.table-cell-1 {
background-color:red;
}
.table-cell-2 {
background-color:green;
}
.table-cell-1 a {
display: inline-table;
background-color:#ccc;
height:100%;
min-height:100%;
}
See JS Fiddle: http://jsfiddle.net/82no4o0x/10/

You have this code:
.table-cell-1 a {
display: inline-table;
background-color:#ccc;
height:100%;
min-height:100%;
}
You're asking the a to be height: 100%. But 100% of what? There is no frame of reference. None of the parents have any height specified.
To see what I mean, make this adjustment to the parent:
.table-cell-1 {
background-color:red;
height: 100px; /* new */
}
Now it should work. See demo: http://jsfiddle.net/82no4o0x/23/
When using percentage heights in CSS you need to specify the height for all parent elements, up to and including body and the root element (html).

Because you haven't defined the table or the table row with a height, when you give the link a height of 100%, the link doesn't know what you want it to be 100% of. Although it looks pretty straight forward to you and me. So first of, try giving your table a fixed height and then making your cells height 100%... But I'm guessing you don't want to do that because you want it to grow or shrink depending on the content within it. I tried a few techniques using position absolute on the cell and positioning it relative to the row, but that didn't work in IE for some reason. So I came up with a bit of a trick/hack using a large top and bottom padding and a negative top and bottom margin.
.table-cell-1 { overflow:hidden }
.table-cell-1 a {
padding:2000px 0;
margin:-2000px 0;
}

Padding missing on one side of scrollable div

Take a look at my snippet.
The parent div has a scrollbar and a child div.
Why is the padding (5px) missing on the right side?
#moh
{
background:red;
overflow-x:auto;
width:100px;
padding:5px; // this padding should be on all 4 sides
}
#moh div
{
width:500px;
height:50px;
background:green;
}
<div id="moh">
<div></div>
</div>
To get the bounty I want to know the reason for the missing padding. Maybe there is a name for this phenomenon. Or may it be a browser bug?
It would be excellent to know the part in the CSS or HTML specification which is responsible for the missing padding. But this is not required to get the bounty (Because I know it's hard to find).
#moh
{
background:red;
overflow-x:auto;
width:100px;
padding:5px;
}
#moh div
{
/* width:500px; */
height:50px;
background:green;
}
<html>
<head>
</head>
<body>
<div id="moh">
<div></div>
</div>
</html>
The padding on the right hand side doesn't appear because, the total width of the parent div is 100px(width) + 10px(padding) while the width for the chid div is explicitly set to 500px.
Since the chid div is a block level element and width property greater than that of the parent, it will move past the parent element and hide the right border from the parent div.
Solutions
either remove the width attribute in the child div (so it will take full width of the parent)
or set the width of the parent to at least 500px which is the width of the child element
The reason for this can tell. It's hard to explain, but I'll try. Your" moh " div width value is 100px," moh " in the div width value is 500px. The order of items on Pages is normally left to right. If you do not apply overflow, you see the overflowing sections :
#moh {
background: red;
width: 100px;
padding: 5px; // this padding should be on all 4 sides
}
#moh div {
width: 500px;
height: 50px;
background: green;
}
<div id="moh">
<div></div>
</div>
As you can see, there's an overflow from left to right. when you give overflow, The Overflow will be hidden automatically. So where's the overflow ? (left ? right ? ) That's why it will try to hide everything from the overflow, that is, the part that goes out when it doesn't fit. The part he's trying to hide is in the padding, so that part doesn't show up.
I'm sorry if I said anything that would be misunderstood. Maybe I helped you understand a little bit.
It happens because #moh is 100px and the inner div is 500px. The solution is to set them both to 500px and wrap them with a 3rd div that is limited to 100px with overflow-x.
#wrapper {
overflow-x: auto;
width: 100px;
}
#moh {
background: red;
width: 500px;
padding: 5px; // this padding should be on all 4 sides
}
#moh div {
width: 500px;
height: 50px;
background: green;
}
<div id="wrapper">
<div id="moh">
<div></div>
</div>
</div>
#wrap
{
overflow-x:auto;
width:100px;
}
#inner
{
background:red;
padding: 15px;
width: 500px;
}
#inner div
{
width:500px;
height:100px;
background:green;
}
<div id="wrap">
<div id="inner">
<div></div>
</div>
</div>
one solution would be this:
I had to add some more HTML but hope it solves your problem
It's because of the html behavior of block element like DIV and css overflow property.
By default html elements flow from left to right.
Browsers by Default behavior is -
If parent DIV have any width property (or specific width
inherited) and no css overflow rule is defined, and if child DIV
have defined width which is more than the parent can accommodate,
then it will overflow and will grow beyond the right edge of parent.
To control how Parent Div will deal with overflowing, css overflow
property can be used. overflow:hidden will instruct browser to crop
the exceeding width div at the edge.
overflow-x:auto will instruct browser that, when child element
exceeded width beyond the edge then add scrollbar at x-axis.
So, in the example case above, the child div is having greater width than parent and it is exceeding of the parent. And parent div is having 'overflow-x:auto' rule defined, the scrollbar is appearing upto the edge of parent.
Since padding is inside the edge of the div, it does not considered.
If you want to have padding on all side of the parent div.
Treat the parent div as a grandparent by adding one more div inside a parent and moving child div in it.
On grandparent div you can add required padding and width.
3 On new parent set width:100% which will expand to fit in a grandparent and setting overflow-x:autorule will add scrollbar when the child div expand beyond the parent width.
So, the code will be something like -
#moh
{
background:red;
width:100px;
padding:5px; // this padding should be on all 4 sides
}
#moh div
{
width:500px;
height:50px;
background:green;
}
div{
box-sizing:border-box;
}
#moh div.moh-container{
width:100%;
overflow-x:auto;
}
<!-- Grand parent Div for padding and width -->
<div id="moh">
<!-- Parent Div width 100% to fit in grandparent and overflow rule -->
<div class='moh-container'>
<!-- child element with exceeding width -->
<div></div>
</div>
</div>

Fixed div width is wider than the screen

I am trying to fix a div with a 50vw width. However, when I fix the div, 50vw acts as if it's 100vw.
In the example below, to get the effect I want, I have to make the target 25vw instead of 50vw. 100vw is wider than the screen.
Here is the jsfiddle. the blue .target container should be half the width of the yellow container.
<div class="main">
.
<div class="content">
<div class="content-wrapper">
<div class="target-containers">
<div class="target">. </div>
</div>
</div>
</div>
</div>
CSS
html, body {
margin: 0;
width:100%;
height: 100%;
}
body {
background-color:gray;
}
.main {
background-color: yellow;
min-height:100vw;
position:relative;
margin-left: 25%;
margin-right:25%;
}
.content-wrappers {
position:relative;
}
.target-containers {
position:relative;
}
.target {
min-width:50%;
width:50%;
position:fixed;
float:left;
background-color:blue;
}
Please read about position: fixed.
It is positioned relative to the initial containing block established by the viewport, except when one of its ancestors has a transform, perspective, or filter property set to something other than none
Who is the initial containing block? (EDIT to clearify this comment)
Please read about identifying the containing block
Note: The containing block in which the root element () resides is a rectangle called the initial containing block. It has the dimensions of the viewport (for continuous media) or the page area (for paged media).
Please read about position: sticky
A stickily positioned box is positioned similarly to a relatively positioned box, but the offset is computed with reference to the nearest ancestor with a scrolling box, or the viewport if no ancestor has a scrolling box.
You could change the position value to sticky like this
.main {
background-color: yellow;
max-height:100vh;
min-height: 100vh;
margin-left: 25%;
margin-right:25%;
overflow-y: auto
}
.target{
min-width:50%;
width:50%;
position:sticky;
background-color:blue;
top: 0;
}
Fiddle Example
If you make an element position:fixed it will break it out of the document flow.
If you remove position: fixed it works as expected as it is inheriting from the parent element.

CSS relative container does not scale with margin-child-elements

I've got the following problem:
I want to have a relative container element that contains some child elements each with margin.
If i dont set the height of the container, it resizes height / width by its containing children.
Problem is that it seems to ignore the margin on them.
here some code:
css:
.container{
position:relative;
}
.child {
position:relative;
float:left;
width:200px;
height:50px;
margin-bottom:20px;
}
html:
<div class="container">
<div class="child">hello world</div>
</div>
The container should now resize height to 50+20 = 70px,
so if i put another element below it should be ok but it isn't.
Margin seems not to resize containers height, how to change this?
Not getting your question quiet well but you are probably missing to clear your floats...
Demo
.container{
position:relative;
border: 1px solid #f00;
overflow: hidden;
}
Alternatively you can also use clear: both;
Demo
Depending on the effect you are trying to achieve, either:
1) Add 'overflow:hidden' to the .container div
or
2) Use padding-bottom instead of margin-bottom on the .child div

Create table with div, 2 fixed columns with same height all the time

I'd like a table created with DIV, this table has 2 fixed columns (that it's ok) but the both columns must have all the time the same height.
The code can be find here : Code on Fiddle
The code :
<style type="text/css">
#container
{
position:relative;
width:100%;
margin:0 auto;
}
#header {
background-color:#5a7fa9;
}
#center {
overflow:hidden;
width:100%;
}
#left {
float:left;
width:200px;
background-color:Gray;
}
#content {
margin-left:200px;
background-color:#a9bbd1;
}
#footer {
background-color:#95adc9;
}
</style>
<div id="container">
<div id="header">header</div>
<div id="center">
<div id="left">left</div>
<div id="content">content<br/><br/></div>
</div>
<div id="footer">footer</div>
</div>
ther is an example

Hi i would like to explain the answer given by Howdy_McGee ..
Add min-height: 100px to #center
Add height: 100% to #left
Add height: 100% to content
he explained the above change which is completely correct.
Seeing your code in jiddle you havent wrote height anywhere in your css style. Therefore all your containers will take height:auto as per the content into it.
you have a div with id='center' this div should have some min-height:100px; and both the inner container should have height:100% by this your elements inside the center div will take height of their parent.
I had preferred you to give the min-height:100px because incase you are putting in dynamic content inside your inner boxes height should increase automatically, therefore if you do not have any content into your div height will stick to 100px.
Hope my explanation makes sense because i am in a bit hurry to type.
You can use this dirty hack (only adding this css):
#center > div {
margin-bottom: -2000px;
padding-bottom: 2000px;
}
Also see your updated example.
=== UPDATE ===
I'll try to explain it:
The padding-bottom uses the background-color. It has to be a heigh value (the minimum different height between the lowest and heighest column). So each column in the center-div add the background-color at the bottom. The negative margin-bottom sets the height back to it's real height. (The entire content is also be visible, even if the minimum height isn't large enough.)

div with 100% height in dynamicly sized element

To describe my item- I have a div element which grows in size if more content is added- also the parent div grows in size as it should be.
Then I have 2 div elements one floated left and the other on the right. I set height to 100% but that don't work. How could I achieve such behavior?
http://109.91.124.194/nucleareducated_2/index.php
This is a typical problem that unfortunately does not have a simple solution. Do a quick Google search for equal height columns and you will see what I mean. Your code is not working because height:100% does not work unless the parent container has a specified height to calculate what 100% is. Without a specified height set, then height:100% defaults to height:auto and you end up with divs that do not expand to the size of the parent.
As you have probably guessed, it's pretty hard to set the height of the parent div because it changes. The answers include setting the height dynamically with Javascript, or more often than not, just faking it so that it appears that the columns expand to the size of the parent.
IMO the best way is to use the css table attribute if you only care about newer browsers, it does not work on IE7 or older.
#containerdiv {
display:table;
}
#childdivleft, #childdivcenter, #childdivright {
display: table-cell;
}
The next best is to use large values for padding and a corresping negative margin on the bottom of the child containers.
#leftdiv,#rightdiv {
padding-bottom: 32767px;
margin-bottom: -32767px;
}
You can also use -
jQuery - Columns of Equal Height with JQuery
several other solutions - CSS - Equal Height Columns?
let me know if this is what you are looking for: tested in chrome*
<html>
<head>
<style>
html, body {
height:100%;
}
</style>
</head>
<body>
<div style="clear: both; height:100%;">
<div class="pageShadow" style="background-color: blue; height: 100%; width: 47px; float: left;"></div>
<div class="pageShadow" style="background-color: blue; height: 100%; width: 52px; float: right;"></div>
<div class="pageShadow" style="background-color: green; margin-left: 47px; margin-right: 52px;"></div>
</div>
</body>
</html>
Maybe this is what you mean? You can add a div around the left and right div if you want an area with 100% height.
CSS:
* { margin:0; padding:0 }
#around { background:yellow; float:left }
#left { float:left; width:40%; background:red }
#right { float:right; width:60%; background:green }
#bottom { clear:both; background:blue }
HTML:
<div>
<div id="around">
<div id="left"></div>
<div id="right"></div>
</div>
<div id="bottom"></div>
</div>
