Answer 1

Probably height: auto should work here.

CSS for #popup :

#popup {
  background-color: #FFF;
  box-shadow: 1px 1px 4px #000;
  display: none;
  height: auto;
  width: 450px;
  font-family: 'Roboto', Arial;
  position: absolute;
  margin: 0 auto;
}

Answer 2

To center a popup to screen you must have the following properties set like this -

#popup {
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  margin: auto;
  position: absolute;
  width: 450px;  // Any fixed width
  height: 300px; // Any fixed height
  ............
  ............
}

Answer 3

use jquery for center the pop up;

<script type="text/javascript" >
    $('#popup').position({
            of: $(window)
        });
</script>
