react css root div full browser height - html

I can't seem to get the react root div to fill the browser page.
I've tried adding the following CSS, and just about every combination of
html, body {
margin: 0;
height: 100%;
}
.fill-height {
min-height: 100%;
height:auto !important; /* cross-browser */
height: 100%; /* cross-browser */
}
#root > [data-reactroot] { height: 100vh }

You should be able to achieve this by setting height to 100% or 100vh of #root instead of #root > [data-reactroot]. This does depend on the rendered structure of your application. You may also need to set the height on multiple elements depending on how nested things are:
#root {
height: 100vh;
}
Here is a StackBlitz showing the functionality in action. You may need to fork it and update it to match more with the structure of your application, but it may be the only issue is you are targetting a child of #root instead of just #root.
Hopefully that helps!

Fix the size of 'html' and 'body' elements to be exactly those of the screen

I often need that html and body elements have the size of the screen. Typically, in the case when I want to have a svg element fit the whole screen.
To achieve that, I saw that it was possible to use CSS code as follow.
html,body{margin:0;padding:0;height:100%;}
The code that I personnaly use is the following one.
html {
height: 100%;
display: flex;
}
body {
flex-grow: 1;
display: flex;
flex-direction: column;
}
Both seem to work well, but I recently had the following remark.
html { height: 100%; display: flex; } is a useless declaration. html height will always be calculated to fit content. Also 100% means 100% of the parent. html has no parent... also applying flexbox to html is useless as it only has 1 child element that is visible: body.
Actually:
I put 100% of html height in order to have it fit the screen height.
I apply flexbox to html in order to be able to use flex-glow: 1 on its child, and have this child filling its parent.
Is there any better to solution than mine?
I personally use this:
html {
display: grid;
min-height: 100%;
}
This will make your body full height by default and will also respect default margin
html {
display: grid;
min-height: 100%;
background: blue;
}
body {
background: red;
}
And you can easily use height:100% on an inner element without issue:
html {
display: grid;
min-height: 100%;
background: blue;
}
body {
background: red;
}
.box {
height: 100%;
border: 5px solid green;
box-sizing: border-box;
}
<div class="box"></div>
I find that whenever working with elements that need to be the full height of the screen height: 100vh is usually a good place to start. VH = viewport height. I use it over height: 100% as depending on the layout 100% doesn't always equal the page height, so with VH you know exactly what you are getting!
With VH you can also then use a calc() in your CSS, so if you needed your body to fill the whole height of the page, but subtract the height of a header for example you could do something like this:
<header style="height: 64px">
<section style="height: calc(100vh - 64px)"

HTML, Body height 100% does not work

Ok, so I have a mobile application with Cordova and AngularJS. For the styling I use Less and Bootstrap.
Problem
In the mobile app I have tried to size my divs with percentage (%). But this does not seem to work. I cannot seem to change the following behavior: The divs are as big as the content inside of them. This problem sounds quite easy and I have tried many options on here (stackoverflow) aswell as on the web. Yet I have not found the solution to fix it and it is getting quite annoying.
I have tried
Adding html, body { height: 100% },
Adding html, body, #canvas { height: 100%}
Adding #canvas { min-height: 100% }
Adding html { height: 100% } body { min-height: 100% }
And a lot of other variations. Using px works, but I don't know how big my mobile device is, so that isn't realy handy.. (I also use bootstrap and some media queries for styling).
Example
When I add elements to my div I get the following behavior:
I want to remove that white empty space, but I can only achieve that when using px instead of %.
Less example:
html, body {
background: transparent;
height: 100%;
margin: 0;
padding: 0;
}
#canvas {
min-height: 100%;
}
body {
-webkit-touch-callout: none; //prevent callout to copy image, etc when tap to hold
-webkit-text-size-adjust: none; //prevent webkit from resizing text to fit
-webkit-user-select: node; //prevent copy paste, to allow, change 'none' to 'text'
min-height: 100%;
margin: 0;
padding: 0;
background-color: #cgiColor;
}
.header {
top: 0px;
width: 100%;
height: 5%;
background: #companyColor;
color: #textColor;
}
.incidentContainer {
background: #appBodyColor;
width: 100%;
height: 70%;
}
.footer {
position: absolute;
color: #textColor;
bottom: 0px;
height: 15%;
width: 100%;
background: #companyColor;
}
Extra information
I am using AngularJS, so my application is a single page application. My index.html looks as follows:
<body oncontextmenu="return false" >
<div class="{{ pageClass}}" ng-view ></div>
<script type="text/javascript" src="cordova.js"></script>
<script data-main="main" src="lib/require.js"></script>
</body>
With of course the standard links to my CSS sheets, and so on.
All the other pages are includes in the 'ng-view' and don't have any or tags. This because they are included.
Solution
The solution was to add the following CSS rule:
div[ng-view]{
height: 100%;
}
This worked, because all divs (except for html & body) are children of this item. Adding the 100% made the div space span to 100% of the screen and thus provides a space for percentage to work.
Credits go to Jai for this answer!
Have you tried to add the following css and set Important attribute
html, body { height: 100% !important }
What seems to me, the directive ng-view is the parent of your application and header, content, footer are loaded in this div. So you have your header div at correct place, your footer is also placed correctly as it is absolutely positioned.
But in case of your content area, that is relative to the ng-view div.
I would recommend you to make it 100% height. Something like:
div[ng-view]{
height: 100%;
}
This most likely is because of the fact that in CSS the 100% is a relative value.
With width the default 100% is the width of the screen, or whatever you are looking at.
Height however does not take the height of the screen as 100%. It needs a solid value.
I think that if you change
html, body {
background: transparent;
height: 100%;
margin: 0;
padding: 0;
}
with
html, body {
background: transparent;
height: 100vh;
margin: 0;
padding: 0;
}
it should work.
The 100vh should set the height of the html to the height of the viewport.
I guess this way works, I have to say though that I myself have not used something to get my page to have a height that is 100% of the screen.
Yay, rendered HTML!
class="incident" is only expanded as large as it needs to be. I believe your fix should be to make that element have a height of 70% (because it will be relative to the whole-page) and then incidentContainer should have a height of 100%.
Percentage heights are relative to the parent element, not the root, so you need to be very aware of any containers, even ones stealthily added by a framework.
Also, if it helps, Jelmergu suggested the vh unit type. This could fit your use case - one "Viewport Height" is equivalent to "1% of the browser's content area". So, 100vh would take up the whole screen. This is true even on deep-level children.

Min-height: 100% is not working

I'm trying to create a div that will expand to 100% of the screen height when there is not enough content for it to do so normally, but will expand normally beyond that if there is enough content. If my div is called container, then whenever I use
#container
{
min-height: 100%;
}
it seems to have no affect on the height at all. When I use
#container
{
height: 100%;
min-height: 100%;
}
it sets the height to a fixed 100%, cutting off any content that would normally be past 100% of the screen height. I'm not sure what I'm doing wrong.
You can try
body, html {
height: 100%;
}
Borrowed from this answer. You can also refer this.
Fiddle
Maybe could you give us a JSfiddle of your HTML ? It would help us helping you.
I think you could use:
#container
{
height: 100%;
overflow: auto;
}
Or play around with position/float/clear.

How to make an element the full height of a page?

Is there a way that I could set a DIV element to take up all the height on the page. Something like:
div.left {
height: 100%;
width: 50%;
background-color: blue;
position: absolute;
top: 0;
left: 0;
}
I've Google'd it a few times but they all seem like really really complicated work arounds for what is probably a really really simple problem with a simple solution.
If the div is a direct child of body, this works:
body, html {height: 100%; }
div { height: 100%; }
Otherwise, you have to keep adding height: 100% to each of it's parents, grandparents,... untill you've reached a direct child of body.
It's simple. For a percentage height to work, the parent must have a specified height(px, %... whichever). If it does not, then it's as if you've set height: auto;
Another way to do it is as you have in your answer: it's to give it an absolute position value, relative to the element that defines the page's height.
This is the simplest way to make a div take up the full height of a page.
height: 100vh;
vh is Viewport Height, and 1vh is equal to 1% of the height of the viewport. See here for more details on this and other units of measurement in CSS.
Make sure you set height: 100% to html and body so that the div has a context for height! Hope that helps.
Pretty sure you need to set the html and body to 100%:
html {
height: 100%;
}
body {
height: 100%;
}
div.left {
height: 100%;
}
Fiddle here.
This problem can be solved using CSS flexbox.
Go through the w3schools documentation of flexbox here and another helpful link css-tricks here
In this scenario.
put display: flex; in the parent div container
div.container{
height: 100%;
display: flex;
}
then in the child div put display: 1;
div.left{
height: 100%;
display: 1;
}
note that if the height of the parent div container is set dynamically, the child div will always have the same height as the parent.

How can I set a fixed height for my entire webpage?

I thought this was a simple fix:
body
{
height: 1054px;
}
html
{
height: 1054px;
}
Wouldn't this set the max height of the page to 1054px? I have also tried these workarounds but they didn't work with what I wanted:
html
{
overflow: hidden;
}
<body><table id = "myTable"><tr><td> ..... </tr></td></body>
#myTable
{
height: 100%;
}
How do I set an absolute height for a webpage? Also I am more interested in why the body and html height calls wouldn't work. I do a lot of position: relative calls, would that have an effect on it?
width and height do set absolute widths and heights of an element respectively. max-width, max-height, min-width and min-height are seperate properties.
Example of a page with 1054px square content and a full background:
html {
min-width: 100%;
min-height: 100%;
background-image: url(http://www.example.com/somelargeimage.jpg);
background-position: top center;
background-color: #000;
}
body {
width: 1054px;
height: 1054px;
background-color: #FFF;
}
However, since you seem to be table styling (urgh), it would probably be far more sensible to set the height of the table to 1054px and let the body adjust itself automatically to encompass the entire table. (Keep the html style proposed above, of course.)
Good question. I’m not sure, but have you tried using a single <div> (or <section>) inside <body>, and setting the width, height and overflow: hidden on that? Browsers might give special treatment to <html> and <body>.
Did you try setting the CSS margin of body to 0? Otherwise there will be some amt (depending on browser) of margin that is included in your page height (and width) but isn't controlled by the height style;
In CSS:
body: { margin: 0; }
IN jQuery:
$('body').css('margin', 0);
