Horizontally and Vertically Center Modal Div IE Issue
- by aherrick
I'm trying to horizontally and vertically center a modal window inside a div. I want it to be cross browser compatible. You can see from the picture below that when I resize IE8 then click, "show modal" button it displays not exactly horizontally centered. This does not seem to be an issue with Chrome. Any thoughts? How would you guys accomplish this?
<html>
<head>
<title>test</title>
<style type="text/css">
*
{
margin: 0px;
padding: 0px;
}
</style>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$('#modal').click(function() {
// overlay
$('<div id="overlay" />').css({
position: 'absolute',
top: 0,
left: 0,
width: '100%',
height: '100%',
backgroundColor: 'black',
opacity: 0
}).appendTo('body');
$('<div id="datamodal" />').css({
backgroundColor: '#FFFFFF',
border: '10px solid #999',
height: '200px',
width: '600px',
position: 'absolute',
top: '50%',
left: '50%',
marginTop: '-120px',
marginLeft: '-320px',
color: '#111111',
fontWeight: 'bold',
padding: '10px',
display: 'none'
}).append('<input type="text" />').appendTo('#overlay');
$('#overlay').fadeTo(300, 0.7);
$('#datamodal').fadeIn(300);
});
});
</script>
</head>
<body>
<input id="modal" type="button" value="show modal" />
</body>
</html>
