How do I get this 'div' to be in the center of the page?
.dialogbox {
position: absolute;
top: 30px;
width: 550px;
border-radius: 4px;
background: #FFFFFF;
margin: auto auto;
overflow: hidden;
display: none;
z-index: 9999;
}
I need to keep the properties' position: absolute; top: 30px; ', as it will appear above other divs, and with a margin at the top of 30px;
