How to center the content of a page.

Hi Ishyoboy,
this is my website page: https://andreagavardi.it/chi-sono-2/

I’m not able to center the rounded picture, the text and the social icons into the [section color=”color2″] because they are all in the right side of the page.
I have tried in every way, with all shortscodes (coloumn,grid and row etc). I really don’t know how to do it… What code do I have to add to the page and where?
I would like also to know how to increase the size of the text.

Thank you for your help.
