How to set flexible height for parent div. In my code popup is there inside div. If I open the popup i want to increase the height of the parent div. I have used height:100% but it is not working. So, How to resolve this issue.
HTML:
<div class="main">
<a href="#" open-popup>Popup</a>
<maincontent class="content">
shadow-root(open)
<popup class="popup"> ..content..</popup>
</maincontent >
</div>
CSS:
.main{
height:100%;
width:100%;
display:table;
border:2px solid #ccc;
}
.content{
display:flex;
justify-content:center;
}
Getting like this:
Expected like this:
You can use auto height
height: auto;
instead of
height:100%;
to not disturb height of parent div
To main class you can use display "block" property instead of "table" and heigth will be "auto" or just don't define it will take automatically take.
<div class="main">
<a href="#" open-popup>Popup</a>
<main class="content">
shadow-root(open)
<div class="popup"> ..content..</div>
</main>
.main{
height:auto;
width:100%;
display:block;
border:2px solid #ccc;
}
.content {
display:flex;
justify-content:center;
}

Im trying to overlap an element with a absolute position .tools outside of its uppermost parent element #canvas_area which has an overflow:scroll, however this doesn't seem to work, but it does work if you remove the overflow:scroll attribute.
HTML:
<div id="canvas_area">
<div class="container">
<div class="blocks">
<div class="tools">
x
</div>
</div>
<div class="blocks">
<div class="tools">
x
</div>
</div>
</div>
</div>
CSS:
#canvas_area{
overflow:scroll; // remove this and it works
height:400px;
width:400px;
background-color:black;
margin: 0 auto
}
.container{
position:relative;
}
.blocks{
overflow:hidden;
width:200px;
height:100px;
background-color:white;
margin-bottom:10px;
}
.tools{
position:absolute;
color:green;
left:-40px;
}
I need #canvas_area to have a scroll, is their a way around this?
here is the jsfiddle: https://jsfiddle.net/2exn6oq5/

I have some child divs placed in a parent div. It looks like that:
Now I need to place an image with a relative size into the red(brown) div.
But every time when I place the image into the div the layouts expands.
And that is a problem for me.
So how can I put an image with a relative size into my div without expanding the div layout?
HTML:
<div class="textContentContainer">
<div class="FirstSectionContentHeader">
<table class="layoutTable"><tr><td class="centerDiv">
<div class="FirstSectionHeaderintroText uppercase">
SOME TEXT
</div>
</td></tr></table>
</div>
<div class="FirstSectionLogoArea">
<img src="../img/Headerlogo.png" alt="Description" class="FirstSectionTitleLogo">
</div>
<div class="FirstSectionIntroText usualText">
ddd
</div>
<div class="FirstSectionBottomLayout">
<img src="../img/basics/Pfeil.png" alt="Pfeil" class="FirstSectionBottomArrow">
</div>
</div>
CSS
.FirstSectionContentHeader{
height:10%;
width: 100%;
font-weight:200;
text-align:center;
background-color: aqua;
}
.FirstSectionLogoArea{
height:10%;
width:100%;
background-color: chartreuse;
}
.FirstSectionTitleLogo{
height:80%;
width:100%;
object-fit:contain;
}
.FirstSectionIntroText {
height:70%;
width:100%;
background-color:white;
}
.FirstSectionBottomLayout{
height:10%;
width:100%;
background-color: brown;
}
.FirstSectionBottomArrow {
height:10%;
width:10%;
object-fit:scale-down;
}
the image has position: staticby default, which is "inserted" in the parent element and "takes some space" there, causing the parent element to become larger. You can give it position: absolute(which requires that the parent element has position: relative) and still use percentage values.
I have a div container in my html page and i want set its height to expand all remaining page in the screen..
How can i do that ??
That's my code :
HTML
<div class="row">
<div id="builder-container" class="col-xs-12 col-lg-9">
<div id="builder-content" > </div>
</div>
</div>
CSS
#builder-container {
background-color: #ccc;
height: 100%;
}
You have to give all of the parent elements, including the div you want to extend, a height of 100%.
Actually it would not get cover your whole page without enough content, but the best way is to give it 'position:absolute/fixed/relative' and give the same div top:whateveryouwant px; and bottom: 0px/0%; width and height :100%
JSFiddle - Edited: Check it now
CSS
body
{
margin:0;
width:100%;
height:100%;
}
#builder-container {
display:block;
position:absolute;
margin-top:5%;
left:0%;
bottom:0%;
background-color: #ccc;
height: 100%;
width:100%;
}
html
<div class="row full_height">
<h1>Test elem</h1>
</div>
css
.full_height {
height: 100vh
}
I'm trying to place two divs one above the other. The top div should stay always visible (not scrolling). The div below contains a list, and if the list is too long, and overflows the window/containing div, the div should be scrollable. When defining the height of the top div, it's good, but the content of the top div may change, so the height should not be fixed (like in this question).
My attempt on Plunker.
Is it possible with pure CSS, without JavaScript calculation?
Edit:
The list should strech to the bottom of the screen/container div.
You need to use some not too obvious CSS trickery to get the behaviour you're after, importantly any scrollable content needs to be within a separate container in a CSS table's cell, with overflow-y set, and a height of 100%. The top cell then needs a height of 1% to auto expand as appropriate.
Then all you need to do is set the tables height and max-height as appropriate.
By using CSS tables, you get a lot more flexibility when it comes to layout calculation/manipulation in terms of relating the sizes of elements
Demo Fiddle
CSS
html, body {
height:100%;
width:100%;
margin:0;
padding:0;
}
.table {
display:table;
table-layout:fixed;
height:100%;
width:100%;
max-height:100%;
}
.row {
display:table-row;
}
.cell {
display:table-cell;
}
.row:first-of-type >.cell {
background:lightgreen;
height:1%;
}
.row:last-of-type >.cell {
background:pink;
}
#list {
height:100%;
overflow-y:auto;
}
HTML
<div class='table'>
<div class='row'>
<div class='cell'>This is text in the <strong>list-head</strong>, it's content may change, so the height of the div shouldn't be fixed, but should stay always visible (not scrolling).</div>
</div>
<div class='row'>
<div class='cell'>
<div id="list">
<div class="list-element">These are list elements.</div>
<div class="list-element">If the list is too long</div>
<div class="list-element">and reaches the bottom</div>
<div class="list-element">the list should be scrollable.</div>
<div class="list-element">(And only the list</div>
<div class="list-element">not together with the <strong>list-head</strong>.)</div>
</div>
</div>
</div>
</div>
Will this work for you ?
<div id="top" >
</div>
<div id="bottom">
</div>
<style>
#top{
display:block;
width:100%;
}
#bottom{
overflow:scroll;
display:block;
height:500px;
width:100%;
}
</style>
use this structure
<div class="main">
<div class="header">
</div>
<div class="content">
</div>
</div>
.main{
height:100%;
}
.header{
height:50px;
position:fixed;
top:0;
background:#454546;
width:100%;
}
.content{
margin-top:53px;
background:#ffffff;
}
Demo
<div id="container">
<div id="content">
//my content
</div>
</div>
#container{
height:100%!important;
min-height:700px!important;
}
#content{
height:100%!important;
}
I have a container div with a content div inside, no matter what I do, I can't get the content div to be the same height as the container div. Am I missing something?
Thanks
<style>
#container{
height:700px !important;
border:1px solid red;
}
#content{
height:100%!important;
border:1px solid green;
}
</style>
<div id="container">
<div id="content">
//my content
</div>
</div>
just add min-height:inherit to content style
#content{
height:100%!important;
min-height:inherit;
}
Add height:100% to html and body
html, body{height:100%}
DEMO
you can add min-height:700px (or inherit) to child div also. I hope it does the trick.
UPDATED DEMO
Add more content to the inner div to check the height:100% effect when content increases.
