height:100vh The . box class has only 100vh which is 100% of the viewport height. When you set the height to 100vh, the box element will stretch its height to the full height of the viewport regardless of its parent height.
Answer: Set the 100% height for parents too And we all know that the default value of the height property is auto , so if we also set the height of <body> and <html> elements to 100%, the resulting height of the container div becomes equal the 100% height of the browser window.
Syntax: height: length|percentage|auto|initial|inherit; Property Values: height: auto; It is used to set height property to its default value.
In CSS3 you could use
height: calc(100% - 60px);
Here is a working css, tested under Firefox / IE7 / Safari / Chrome / Opera.
* {margin:0px;padding:0px;overflow:hidden}
div {position:absolute}
div#header {top:0px;left:0px;right:0px;height:60px}
div#wrapper {top:60px;left:0px;right:0px;bottom:0px;}
div#left {top:0px;bottom:0px;left:0px;width:50%;overflow-y:auto}
div#right {top:0px;bottom:0px;right:0px;width:50%;overflow-y:auto}
"overflow-y" is not w3c-approved, but every major browser supports it. Your two divs #left and #right will display a vertical scrollbar if their content is too high.
For this to work under IE7, you have to trigger the standards-compliant mode by adding a DOCTYPE :
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title></title>
<style type="text/css">
*{margin:0px;padding:0px;overflow:hidden}
div{position:absolute}
div#header{top:0px;left:0px;right:0px;height:60px}
div#wrapper{top:60px;left:0px;right:0px;bottom:0px;}
div#left{top:0px;bottom:0px;left:0px;width:50%;overflow-y:auto}
div#right{top:0px;bottom:0px;right:0px;width:50%;overflow-y:auto}
</style>
</head>
<body>
<div id="header"></div>
<div id="wrapper">
<div id="left"><div style="height:1000px">high content</div></div>
<div id="right"></div>
</div>
</body>If you need to support IE6, use JavaScript so manage the size of the wrapper div (set the position of the element in pixels after reading the window size). If you don't want to use JavaScript, then this can't be done. There are workarounds but expect a week or two to make it work in every case and in every browser.
For other modern browsers, use this css:
position: absolute;
top: 60px;
bottom: 0px;
great one... now i have stopped using % he he he... except for the main container as shown below:
<div id="divContainer">
<div id="divHeader">
</div>
<div id="divContentArea">
<div id="divContentLeft">
</div>
<div id="divContentRight">
</div>
</div>
<div id="divFooter">
</div>
</div>
and here is the css:
#divContainer {
width: 100%;
height: 100%;
}
#divHeader {
position: absolute;
left: 0px;
top: 0px;
right: 0px;
height: 28px;
}
#divContentArea {
position: absolute;
left: 0px;
top: 30px;
right: 0px;
bottom: 30px;
}
#divContentLeft {
position: absolute;
top: 0px;
left: 0px;
width: 250px;
bottom: 0px;
}
#divContentRight {
position: absolute;
top: 0px;
left: 254px;
right: 0px;
bottom: 0px;
}
#divFooter {
position: absolute;
height: 28px;
left: 0px;
bottom: 0px;
right: 0px;
}
i tested this in all known browsers and is working fine. Are there any drawbacks using this way?
div {
height: 100%;
height: -webkit-calc(100% - 60px);
height: -moz-calc(100% - 60px);
height: calc(100% - 60px);
}
Make sure while using less
height: ~calc(100% - 60px);
Otherwise less is no going to compile it correctly
You can do something like height: calc(100% - nPx); for example height: calc(100% - 70px);
