ie7下相对定位为什么无效？

nbsp;html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
		Keep Me in		Keep Me in

.btn{
position:relative;
}
.btn:hover{
top:1px;
display:inline;
}

relative无法对block元素起效？

nbsp;html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
