I'm stuck with displaying a React component named "home" that take 100% of the height of my screen.
Whatever I use CSS or React inline style it doesn't work.
In the example below, html, body and #app are set to height: 100% in CSS. For .home I used inline style (but whatever I used CSS or inline style is the same):
The issue seems to come from <div data-reactroot data-reactid='1'> that is not set with height: 100%.
If I hacked it with Chrome developer tool, it's work:
So what is the proper way to display a full height component in React ?
Any help is welcome :)
html, body, #app, #app>div {
height: 100%
}
This will ensure all the chain to be height: 100%
You could also do:
body > #root > div {
height: 100vh;
}
try <div style = {{height:"100vh"}}> </div>
It annoys me for days. And finally I make use of the CSS property selector to solve it.
[data-reactroot]
{height: 100% !important; }
Despite using of React here - elements layout is completely html/css feature.
The root cause of the issue is in how height property in css works. When you are using relative values for height (in %) - this means that height will be set in relation to its parent.
So if you have a structure like html > body > div#root > div.app - to make div.app 100% height all its ancestors should have 100% height. You may play with next example:
html {
height: 100%;
}
body {
height: 100%;
}
div#root {
height: 100%; /* remove this line to see div.app is no more 100% height */
background-color: indigo;
padding: 0 30px;
}
div.app {
height: 100%;
background-color: cornsilk;
}
<div id="root">
<div class="app"> I will be 100% height if my parents are </div>
</div>
Few arguments:
Usage of !important - despite some time this feature is useful in ~95% of cases, it indicates a poor structure of html/css. Also, this is not a solution to the current problem.
Why not position: absolute. Property positon is designed to change how the element will be rendered in relation to (own position - relative, viewport - fixed, nearest parent whos position is not static - absolute). Ans despite position: absolute; top: 0; right: 0; bottom: 0; left: 0; will result in the same look - it also pushes you to change parents position to something not static - so you need to maintain 2 elements. That also causes parent div be collapsed in a line (0-height), and inner - full screen. That makes confusion in element inspector.
I managed this with a css class in my app.css
.fill-window {
height: 100%;
position: absolute;
left: 0;
width: 100%;
overflow: hidden;
}
Apply it to your root element in your render() method
render() {
return ( <div className="fill-window">{content}</div> );
}
Or inline
render() {
return (
<div style={{ height: '100%', position: 'absolute', left: '0px', width: '100%', overflow: 'hidden'}}>
{content}
</div>
);
}
#app {
height: 100%;
min-height: 100vh;
}
Always full height of view min
While this may not be the ideal answer but try this:
style={{top:'0', bottom:'0', left:'0', right:'0', position: 'absolute'}}
It keeps the size attached to borders which is not what you want but gives you somewhat same effect.
body{
height:100%
}
#app div{
height:100%
}
this works for me..
<div style={{ height: "100vh", background: "#2d405f" }}>
<Component 1 />
<Component 2 />
</div>
Create a div with full screen with background color #2d405f
I had the same issue displaying my side navigation panel height to 100%.
My steps to fix it was to:
In the index.css file ------
.html {
height: 100%;
}
.body {
height:100%;
}
In the sidePanel.css (this was giving me issues):
.side-panel {
height: 100%;
position: fixed; <--- this is what made the difference and scaled to 100% correctly
}
Other attributes were taken out for clarity, but I think the issue lies with scaling the height to 100% in nested containers like how you are trying to scale height in your nested containers. The parent classes height will need to be applied the 100%. - What i'm curious about is why fixed: position corrects the scale and fails without it; this is something i'll learn eventually with some more practice.
I've been working with react for a week now and i'm a novice to web developing, but I wanted to share a fix that I discovered with scaling height to 100%; I hope this helps you or anyone who has a similar issue. Good luck!
For a project using CRNA i use this
in index.css
html, body, #root {
height: 100%;
}
and then in my App.css i use this
.App {
height: 100%;
}
and also set height to 100% for a div within App if there is one eg-
.MainGridContainer {
display: grid;
width: 100%;
height:100%;
grid-template-columns: 1fr 3fr;
grid-template-rows: 50px auto;
}
Try it to solve your problem
<div style = {{height:"100vh"}}> </div>
Adding this in the index.html head worked for me:
<style>
html, body, #app, #app>div { position: absolute; width: 100% !important; height: 100% !important; }
</style>
I had trouble until i used the inspector and realized react puts everything inside a div with id='root' granting that 100% height along with body and html worked for me.
CRA has a #root div to which we render our react app, so it should also be considered a parent div and give appropriate height according to your need. This answer is based on my experience with a similar situation and giving 100% height to #root helped me fix the height issue with one of it's child element.
This depends on the layout of your app, in my case the child was not able to takeup the given height because #root(parent) div had no specified height
Funny how this works since I thought html was the one with not full height, turns out it was the body.
Just add the below css in index.css:
body{
height: 100%;
}
There is an existing body tag? Add it in there!
I'm currently trouble shooting in NextJS 13 & Tailwind to achieve this.
There's an additional layer of < div>'s that I'm unable to locate generated from Next's new AppDir.
One way to trouble shoot that nobody mentioned, which is easy to overlook is:
Open your Web Dev Tools and modify each ancestor to height:100% or in Tailwind 'h-full' and you'll save time to see if height full is the appropriate solution for your use case. I was quickly able to find out my footer component overlaps my div with this method instead of wasting time.
Edit: Reason for Next 13 user https://github.com/vercel/next.js/issues/42345
try using !important in height. It is probably because of some other style affecting your html body.
{ height : 100% !important; }
also you can give values in VP which will set height to viee port pixel you mention likeheight : 700vp; but this wont be portable.
I can't seem to get the Leaflet full screen plugin to work appropriately in Google Chrome when I set the CSS position property for the map div.
Here's a JS Bin to demonstrate my problem.
See the code:
#map { position:absolute; top:100px; bottom:50px; width:100%; }
On Firefox and IE, the map correctly goes to full screen (i.e. expands beyond the dimensions of the map div), but on Chrome, the full screen gets constrained by the top and bottom properties of the map div.
Any ideas on how to overcome this problem?
Thanks!

Edited 8/14/14: Thanks #FranceImage for the great answer, which worked like a charm. I'm still learning CSS and thus I'm sure there are always better ways to do things than I have done. For example, I'm not sure how to use the float property to achieve the same effect that I have with position: absolute on my page here.
How do I change the following code to use the float property instead of position: absolute to achieve the desired effect of having my map NOT overlap the header and sidebar? Thank you!
#map2 {
height: 100%;
width: 100%;
}
#mapcontain {
position: absolute;
top: 125px;
bottom: 50px;
left: 16%;
right: 0;
width: 100%;
}
For the plugin to work, you can't change the following
#map { position:absolute; top:0; bottom:0; width:100%; }
You will have to wrap the in a container (another div) where you will apply your positioning css
<div id="content">
<div id="map"></div>
</div>
Note: I would not use absolute positioning for a page layout.
Absolute position benefit is that the element is taken out of the normal flow and can cover other elements. It is usually used for dialog boxes and popups.
Go for float position.
this is all over the stackoverflow,but it doesn't work for me.
using twitter bootstrap 3, i need to set the jumbotron class div to full display height.
this is my test site:
http://test.ulkas.eu/
i read i shall include
html {
height: 100%;
}
body {
min-height: 100%;
padding-top: 50px;
}
but it still doesn't work. maybe i got some syntax error somewhere?
In order to apply 100% height property to inner divisions you need to mention the same property to all the parent divs. So add
body{height: 100%;min-height:100%;padding-top:50px;}
.jumbotron{height:100%;}
to your body as well as to jumbortron class
The height of your html / body will always only be the height of your content - those tags behave slightly different to standard div / block tags. To get something to be truly 100% high your best bet is to remove it from the standard flow of the page using position: absolute / fixed, then set your div to be 100% high. Something like this:
.fullheight {
position: absolute;
top: 0px;
left: 0px;
height: 100%;
width: 100%;
z-index: 2;
}
I think it's always worth setting a z-index on anything I position outside the normal page flow, allows you to control which parts appear on top of others.
I'm trying to create a vertically positioned DIV by percentage. I have the parent container to set to relative and the content div set to absolute. This works fine when I position the content div with pixels, but when I try percentages the percentages are disregarded:
.container {
position: relative;
}
.content {
position: absolute;
left: 10%;
top: 50%;
}
<div class="container"><div class="content"> This is the content div. It should be 10% from the left of the container div.
</div></div>
The content div appears at the top of the page, disregarding the 50% vertical placement. What am I missing? Thanks in advance!
The absolutely positioned element is taken out of the natural flow of the document which means your container has zero height and width.
10% and 50% of that zero height and width are, of course, zero.
If you give your container a height and width, your percentage positions will start to work as you want.
Here is a working example.
.container { position: relative; width:500px; height:500px; }
Welp, my first post in SE. For those of you seeing this in the future, you can actually use viewport height as a measure of percentage.
.container {
position: relative;
top: 10vh; // 10% of height from top of div
}
You will likely need to add height: 100% to your .container div:
.container { height: 100%; position: relative; }
and possibly all the ancestor elements:
html, body { height: 100%; }
#Jaime Dixon's answer was great. Beautiful, two great concepts given there.
The percentage, the relative units are relative TO SOMETHING, you must understand what's the reference container to which those values are calculated.
Even if you have a container, there CAN BE an arbitrary behavior if the container has it's dimensions as "auto". So, to have a predictable behavior, be sure that the container has a dimension better than simply saying "auto". OR, if your container also has 100%, and its parent and so on, make sure you have a css instruction in which you have specified the height of the elements html, body:
example:
html, body {
height: desired_value;
}
I know its easy to stack images on top of one another but I just wondered if this could be achieved but maintaining a fluid image? As soon as I use the position attribute, I have to supply a width. Then the image won't re-size with the browser.
Thanks for any help.

You could of course use width: 100%;. Also, you wouldn't need to put them inside divs if you just specify display: block; on the img element. You may have to specify max-width, but that depends on your particular application and required browser support.
A width : 100% works with position : absolute if display : block
Your problem is likely that you have only absolutely positionned img in your div, so its dimensions are null (because positioning rules.)
Two way to solve this :
make one img not absolutely positionned. Its dimensions will be be dimensions of the parent div
use a transparent img, with position : relative, with the same dimension than your real imgs : it's quite dirty, but it'll set the parent div dimensions.
These'll work only if your imgs' dimensions are the same. Otherwise, you must use a JS solution.
Make the photos the background on either an empty <img> or <div> with something like this
.container {
position: relative;
height: 400px;
width: 100%;
}
.container > div {
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
}
<div class="container">
<div style="background: url('myimage1.jpg');"><!-- nothing --></div>
<div style="background: url('myimage2.jpg');"><!-- nothing --></div>
<div style="background: url('myimage3.jpg');"><!-- nothing --></div>
</div>
