If the effect you want is to center in the center of the screen no matter where you've scrolled to, it's even simpler than that:

In your CSS use (for example)

div.centered{
  width: 100px;
  height: 50px;
  position:fixed; 
  top: calc(50% - 25px); // half of width
  left: calc(50% - 50px); // half of height
}

No JS required.

In order to get the popup exactly centered  it s a simple matter of applying a negative top margin of half the div height  and a negative left margin of half the div width  For this example  like so   div       position  fixed      top  50       left  50       transform  translate -50   -50        width  50
