I didnt check it well yesterday
@goldpix, margin: 0px; is not right way to right. It should be margin:0;
@neil, try that one,
HTML Code:
<html>
<head>
<style>
.username{
position: relative;
margin: 0;
}
</style>
</head>
<body>
<div class = "username">
<form class = "username">
<input type = "text" name = "username" class = "field"
value = "username" onfocus="if (this.value==this.defaultValue) this.value='';" onblur= "if(this.value=='')this.value=this.defaultValu e"/>
</form>
</div>
</body>
</html>
