page will not stay centred as browser window shrinks

Hello All,

I am trying to get the "centre" dot to stay in the middle and have the page scale by the height property, but I cannot make it work.  I have tried every combination of 'centre stage' and 'responsive scaling' I can think of but nothing seems to work.  This is what I want it to look like:

Thanks in advance and all the best!
