dividing the screen to 4 Quarters doesn't work - html

I am dividing my screen to 4 Quarters but it doesn't work with all screen resolutions.I need it to always be 4quarters even by changing the window size.
here is the code:
body{
height:800px;
}
div{
position:relative;
border:1px solid red;
width:49.7%;
height:49.7%;
}
#Q1,#Q3{
float:left;
}
#Q2,#Q4{
float:right;
}
</style>
</head>
<body>
<div id="Q1"> </div>
<div id="Q2"> </div>
<div id="Q3"> </div>
<div id="Q4"> </div>
</body>

Use this CSS to make the height 100% and quarter it:
body{
height:100%;
}
html {
height: 100%;
}
div{
position:relative;
border:1px solid red;
width: 50%;
height: 50%;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
#Q1,#Q3{
float:left;
}
#Q2,#Q4{
float:right;
}

The computed width of the boxes exceeds the total available space in lower screens. This is because the border of 1px around the elements.
You could give the div elements a box-sizing: border-box; declaration so that their width would be calculated including padding and borders.
Example Here
div {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
In addition, if you want to resize the height of the boxes with the respect to the height of the body, note to set height: 100% on body and html as well.
You have to specify the height of html to get height: 100% to work for the <body>. This because a percentage value of height property is relative to the height of box's containing block.
Updated Example Here
html, body {
height: 100%;
padding : 0;
margin : 0; /* Remove the default 8px margin around the body */
}
Also note that UAs apply a default margin to the <body> by default. Make sure you have reset the user agent stylesheet.

input element, display bock

Why is input element does not take up 100% of the width of its container automatically after changing its display to block? Are there some other factors which also have an influence on that? Thanks. Demo see below:
some explanation: 1. I comment out width:100% intentionally because block level element is supposed to take up 100% of its container width.
#container {
width: 300px;
margin: auto;
background-color: red;
}
input[type="text"] {
display: block;
opacity:0.5;
/*width:100%;*/
}
<body>
<section>
<div id="container">
<input type="text">
</div>
</section>
</body>
I'm not an expert, but I'm pretty sure it's because you have commented out width:100%. try decommenting that then it should work
#container {
width: 300px;
margin: auto;
background-color: red;
}
input[type="text"] {
display: block;
opacity:0.5;
width:100%;
}
Changed the code check now
#container {
width: 300px;margin: auto;
background-color: red;
}
input[type="text"] {
opacity:0.5;
width:100%;
border-width:0;
padding:0;
}
<body>
<section>
<div id="container">
<input type="text">
</div>
</section>
</body>
The input element by default has a border: 2px and a padding: 1px 0 in google chrome
When you were actually applying a width of 100%, the input actually had a width greater than the actual div outside covering it
width of input(set to width of div) + border + padding > width of div
There is a tiny little white area on the right, in case you uncomment width:100% in your code. That white area actually is the input. If you set the border to zero that's really enough to fix things
#container {
width: 300px;
margin: auto;
background-color: red;
}
input[type="text"] {
display: block;
opacity: 0.5;
width: 100%;
border: 0
}
<body>
<section>
<div id="container">
<input type="text">
</div>
</section>
</body>
Default size of input is 20, so if you do not define size or css rule for your input automatically its size is 20.
The best solution is adding width.
try this code:
#container
{
width: 300px;
margin: auto;
background-color: red;
}
input[type="text"]
{
display: block;
opacity:0.5;
width:100%;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
If you want to be responsive it is better to add box-sizing to all element like this:
*
{
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}

100% height goes a few pixels off the page?

I'm trying to make a box 100% height of the page. But in both Chrome and IE, the following extends a few pixels off the bottom of the page so I have to scroll. Why? Why is there a scrollbar here?
<!doctype html>
<html >
<head>
<style type="text/css">
html, body
{
margin: 0px;
padding: 0px;
height: 100%;
}
div {
border:5px solid black;
height: 100%;
}
</style>
</head>
<body >
<div >This flows a few pixels off the bottom of the page</div>
</body>
</html>
It goes a few pixels off the page because you're including a 5px border. The body of the div is 100% the height of the page, but the border sits outside of that, adding 10px total height to the page alongside the 100% height. So, on a 1000px page the height of your div will be 1010px. Remove the border and it'll be exactly the right height.
div {
height: 100%;
}
If you still want the border, but not the unwanted extra height you can use the box-sizing: border-box property to place it inside the boundaries of the div
div {
height: 100%;
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
}
...and here is another alternative for you :
html,body
{
height:100%;
margin:0;
padding:0
}
div
{
border:5px solid black;
display:block;
height:-moz-calc(100% - 10px);
height:-webkit-calc(100% - 10px);
height:calc(100% - 10px);
width:calc(100% - 10px)
}
Enjoy!
You can keep your current settings WITH 5px border by declare border-box property for all major browsers:
div
{
height:100%;
box-sizing:border-box !important;
-moz-box-sizing:border-box !important;
-webkit-box-sizing:border-box !important;
}
Since you are dealing with 100% div size it's highly recommended to add the !important so you won't get any conflict with other properties.

div height to fill the whole page

I have a div and I want it to fill the whole page without any horizontal or vertical scrolling.
The html is like:
<body>
<div class="container">
</div>
</body>
and the css like:
body{
background: #222;
margin:0;
padding: 0;
}
.container{
margin:0 auto;
padding:20px;
width:800px;
background: rgba(20,20,20,0.2);
height: 100vh;
}
Normally with vh it works, but because of some padding applied on container it doesn't work. So what technique can I use to solve this problem?
The JSFiddle is here
Try using box-sizing: border-box on your .container element. Doing so will have the padding and border of an element included with width and height assignments.
.container {
box-sizing: border-box;
margin: 0 auto;
padding: 20px;
width: 800px;
background: rgba(20,20,20,0.2);
height: 100vh;
}
This has to do with the way that css adds the padding to the height to calculate the total height. There's one quick and flexible fix for all of your elements though, as explained in Paul Irish's box-sizing:
/* apply a natural box layout model to all elements, but allowing components to change */
html {
box-sizing: border-box;
}
*, *:before, *:after {
box-sizing: inherit;
}
Not Sure Will this help you but you can give it a try-
give position relative to your body and position fixed to your div.container with width 100% and height 100%.
body{
background: #222;
margin:0;
padding: 0;
position:relative;
}
.container{
position:fixed;
left:0;
top:0;
width:100%;
background: red;
height: 100%;
}
Box-sizing FTW! If you need to include the padding as part of the elements dimensions then box-sizing: border-box is your only hope.
FWIW you should be aware that Viewport Units are not fully supported so if you need something more cross-browser you can easily avoid using 100vh by using 100% instead.
E.G:
html, body {
height:100%;
min-height:100%;
}
body{
background: #222;
margin:0;
padding: 0;
}
.container{
margin:0 auto;
padding:20px;
width:800px;
background: red;
height: 100%;
box-sizing: border-box;
}
<div class="container">
</div>

Two divs bottom div to height adjust with browser window [duplicate]

This question already has answers here:
Make a div fill the height of the remaining screen space
(41 answers)
Closed 8 years ago.
I have a header div and a div underneath it. I need the div underneath the header div to adjust depending on the height of the browser window size.
In CSS, when I add height:100% it creates a scroll bar at the side of the page. When I adjust the percentage of the width, spacing at the bottom of the page constantly changes because it is done with percentages.
I would like the div below the header to always adjust with the window size in height with no spacing at the bottom.
How do I do this?
Here is the Fiddle
JS Fiddle
I am not sure why but in JSFiddle the bottom div is not extending height: 100%
here is the code:
HTML
<div class = "main">
Header
</div>
<div class="left">
Bottom Div
</div>
CSS
.main {
width:100%;
height:60px;
border: solid;
}
.left {
height: 100%;
width: 300px;
border:solid;
}
try to use something like this code
html:
<div class = "main">
Header
</div>
<div class="left">
Bottom Div
</div>
css:
* {
-webkit-box-sizing:border-box;
-moz-box-sizing:border-box;
box-sizing:border-box;
}
html, body {
height:100%;
}
body {
padding:60px 0 0 0; /* 60 — header height*/
margin:0;
}
.main,
.left {
border:1px solid #000;
}
.main {
width:100%;
height:60px;
margin-top: -60px; /* 60 — header height*/
}
.left {
height: 100%;
width: 300px;
}
You have a few options to achieve the layout you would like.
There are plenty of answers that address your problem from this similar question:
Make a div fill the height of the remaining screen space
However, here is my solution:
Just change your CSS a bit
body, html {
height: 100%;
padding: 0;
margin: 0;
}
.main {
width:100%;
height:60px;
border: solid;
position: absolute;
background-color: #fff;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
.left {
height: 100%;
width: 300px;
border:solid;
-moz-box-sizing: border-box;
box-sizing: border-box;
padding-top: 60px;
}
The box-sizing will prevent the padding-top and the borders from pushing the dimensions outside the browser window. The body,html height: 100%; is needed to allow other items to be 100% height (why your fiddle wouldn't work).
CSS allows you to do some basic math, so the following would help you:
Given that your header has a fixed height of 60px:
.left {
height: calc(100% - 60px);
}
Edit: you also have some extra padding and borders that you might want to take into consideration while calculating. Although I'm not a big fan of hard-coding values like that.
Try this in your style sheet
CSS
.left {
height: 100vh;
width: 100%;
border:solid;
}

DIV width in % and padding

I have 2 DIVs next to each other (A to the left and B to the right) within a container of 980px wide. I set a width of 50% for both A and B which works great.
Question: I'd like to add some padding-right to DIV A so that the text in it doesn't touch the text of div B. If I do that I need to adjust the % of the DIV (i.e. to 48%). Is there a way to avoid that? (i.e. get the % automatically adjusted based on the padding)
yeah, you can use the box-sizing property. By setting:
box-sizing: border-box;
The width property will set the total width (including borders and padding), so for example a div with:
div {
width:500px;
padding: 20px;
border: 10px solid blue;
box-sizing: border-box;
}
would have a visual overall width of 500px, rather than a default width of 500 + 40 + 20 = 560px.
For reference: http://css-tricks.com/box-sizing/
You can do it by using one more wrapping div:
<div class="wrapper">
<div class="inner">
<div class="left"></div>
<div class="right"></div>
</div>
</div>
.wrapper { width: 960px; }
.inner { padding: 1em; }
.left, .right { width: 50%; float: left; }
Or use box-sizing that makes calulations very easy.
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
It changes the rendering of paddings and border so that they are included in the width rather than added to it.
If you would like to add padding without reducing the width of the div, you can use: box-sizing: border-box; More info
e.g.
-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box; /* Firefox, other Gecko */
box-sizing: border-box; /* Opera/IE 8+ */
This will make your div the desired width (50%), and the padding will be subtracted rather than added to the div. Beware this is a CSS3 property and won't work in all versions of IE:
http://caniuse.com/css3-boxsizing
HTML
<div class="tbl">
<div class="row">
<div class="cell">A</div>
<div class="cell">B</div>
</div>
</div>
CSS:
.tbl{
display:table;
border-spacing:5px;
}
.row{
display:table-row;
}
.cell{
display:table-cell;
width:50%;
}
for width, margin & padding values use % or em values
Have a look at this code
.container {
max-width: 980px;
}
section {
float: left;
margin: 0.0122448; /* 10px ÷ 980px */
width: 0.479591; /* 470px ÷ 660px */
}
aside {
float: right;
margin: 0.0122448; /* 10px ÷ 980px */
width: 0.479591; /* 470px ÷ 980px */
}

You can apply box-sizing:border-box to the divs with padding.
-moz-box-sizing: border-box;
box-sizing: border-box;
Live demo
From MDN:
border-box:
The width and height properties include the padding and border, but not the margin.
box-sizing is supported all the way back to IE8.
You have to use box-sizing:border-box; beacuse using border-box; will give you a look of box with border & it will manage space for border by itself . you can give width and color of your border by yourself border:2px solid black; . And thus, the content of your both divs can be diffrentiated.
