Center a div relative to parent div

Hi,

In this post I will write some codes to help center a div relative to a parent div. This is unlike the my earlier post which centers the div relative to the viewport/window. Lets begin.

DEMO

HTML Codes

<!DOCTYPE html>

Center a div relative to viewport

Hi,

Here I will write some codes that will help center a div relative to the viewport. Let's begin with centering a div relative to viewport. The viewport is the display area for a web page on screen. Here you will find information about centering a div on the screen, i.e. center to the whole viewing window.

HTML Codes

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>How to ...</title>
<style>
#child {
width:300px;
height:300px;
background:green;
position:fixed;
left:50%;
top:50%;
margin-left:-150px;
margin-top:-150px;
}

#parent {
display: block;
position: absolute;
width: 400px;
height: 400px;
background: red;
bottom: 0;
left: 0;
}
</style>
</head>
<body>
<div id="parent">
I am parent div.
<div id="child">Always center no matter where the Parent div is</div>
</div>
</body>
</html>
