I have an html page :
<html>
<head>
<title>
All Time Set Window
</title>
</head>
<body>
<div align="center" style="width:1000px; height:100%; margin-left:auto; margin-right:auto;">
<div style="width:100%; height:20%; background-color:#F8E0E0; float:top;">
<div align="center">This is Header</div>
</div>
<div style="width:100%; height:60%; background-color:#F5F6CE;">
<div align="center" style="width:70%; background-color:#E3F6CE; float:left;">This is Left Frame</div>
<div align="center" style="width:30%; background-color:#E0E0F8; float:right;">This is Right Frame</div>
</div>
<div style="width:100%; height:20%; float:bottom; background-color:#F8E0E0;">
<div align="center">This is Footer</div>
</div>
</div>
</body>
</html>
I have used Margin-left & Margin-right to auto for taking div to center. This is working in Mozilla & not in Explorer. What is solution for the same.
