I want to divide my page into four equal parts, each of same height and width (50-50%).
I don't want to use JavaScript. I want blocks (<div>s) to be resized automatically (and relatively) if the browser window is resized.
I have not worked with CSS for a long time. I've no idea how to handle this.
I did not want to add style to <body> tag and <html> tag.
.quodrant{
width: 100%;
height: 100vh;
margin: 0;
padding: 0;
}
.qtop,
.qbottom{
width: 100%;
height: 50vh;
}
.quodrant1,
.quodrant2,
.quodrant3,
.quodrant4{
display: inline;
float: left;
width: 50%;
height: 100%;
}
.quodrant1{
top: 0;
left: 50vh;
background-color: red;
}
.quodrant2{
top: 0;
left: 0;
background-color: yellow;
}
.quodrant3{
top: 50vw;
left: 0;
background-color: blue;
}
.quodrant4{
top: 50vw;
left: 50vh;
background-color: green;

</html>try this... obviously you need to set each div to 25%. You then will need to add your content as needed :) Hope that helps.
<html>
<head>
<title>CSS devide window by 25% horizontally</title>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
<style type="text/css" media="screen">
body {
margin:0;
padding:0;
height:100%;
}
#top_div
{
height:25%;
width:100%;
background-color:#009900;
margin:auto;
text-align:center;
}
#mid1_div
{
height:25%;
width:100%;
background-color:#990000;
margin:auto;
text-align:center;
color:#FFFFFF;
}
#mid2_div
{
height:25%;
width:100%;
background-color:#000000;
margin:auto;
text-align:center;
color:#FFFFFF;
}
#bottom_div
{
height:25%;
width:100%;
background-color:#990000;
margin:auto;
text-align:center;
color:#FFFFFF;
}
</style>
</head>
<body>
<div id="top_div">Top- height is 25% of window height</div>
<div id="mid1_div">Middle 1 - height is 25% of window height</div>
<div id="mid2_div">Middle 2 - height is 25% of window height</div>
<div id="bottom_div">Bottom - height is 25% of window height</div>
</body>

Tested and works fine, copy the code above into a HTML file, and open with your browser.
Some good answers here but just adding an approach that won't be affected by borders and padding:
<style type="text/css">
html, body{width: 100%; height: 100%; padding: 0; margin: 0}
div{position: absolute; padding: 1em; border: 1px solid #000}
#nw{background: #f09; top: 0; left: 0; right: 50%; bottom: 50%}
#ne{background: #f90; top: 0; left: 50%; right: 0; bottom: 50%}
#sw{background: #009; top: 50%; left: 0; right: 50%; bottom: 0}
#se{background: #090; top: 50%; left: 50%; right: 0; bottom: 0}
</style>
<div id="nw">test</div>
<div id="ne">test</div>
<div id="sw">test</div>
<div id="se">test</div>
Similar to other posts, but with an important distinction to make this work inside a div. The simpler answers aren't very copy-paste-able because they directly modify div or draw over the entire page.
The key here is that the containing div dividedbox has relative positioning, allowing it to sit nicely in your document with the other elements, while the quarters within have absolute positioning, giving you vertical/horizontal control inside the containing div.
As a bonus, text is responsively centered in the quarters.
HTML:
<head>
<meta charset="utf-8">
<title>Box model</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1 id="title">Title Bar</h1>
<div id="dividedbox">
<div class="quarter" id="NW">
<p>NW</p>
</div>
<div class="quarter" id="NE">
<p>NE</p>
</div>
<div class="quarter" id="SE">
<p>SE</p>
</div>?
<div class="quarter" id="SW">
<p>SW</p>
</div>
</div>
</body>
</html>
CSS:
html, body { height:95%;} /* Important to make sure your divs have room to grow in the document */
#title { background: lightgreen}
#dividedbox { position: relative; width:100%; height:95%} /* for div growth */
.quarter {position: absolute; width:50%; height:50%; /* gives quarters their size */
display: flex; justify-content: center; align-items: center;} /* centers text */
#NW { top:0; left:0; background:orange; }
#NE { top:0; left:50%; background:lightblue; }
#SW { top:50%; left:0; background:green; }
#SE { top:50%; left:50%; background:red; }
If you want to have control over where they are placed separate from source code order:
<div id="NW"></div>
<div id="NE"></div>
<div id="SE"></div>?
<div id="SW"></div>
html, body { height:100%; margin:0; padding:0 }
div { position:fixed; width:50%; height:50% }
#NW { top:0; left:0; background:orange }
#NE { top:0; left:50%; background:blue }
#SW { top:50%; left:0; background:green }
#SE { top:50%; left:50%; background:red } ?
Note: if you want padding on your regions, you'll need to set the box-sizing to border-box:
div {
/* ... */
padding:1em;
box-sizing:border-box;
-moz-box-sizing:border-box;
-webkit-box-sizing:border-box;
}
…otherwise your "50%" width and height become "50% + 2em", which will lead to visual overlaps.
