<<I think you might have been on a 17 inch monitor when you viewed it so you wouldn’t see what I mean.>>

no, I simply don't read well at 7am I fear ) I only saw horizontal center. My example shows the box nailed 50px from the top.

I must admit that from memory I can't tell any solution that centers vertically without requiring to calculate size, so your solution does not look complicated anymore regarded that it centers in the viewport.
