Can not center an element (Enfold Iconbox)

Hi there,

I am trying to get my simple iconbox centered within a fullwidth container, but it remains floated to the left, no matter what I try.

I have tried everything with custom CSS as well as the Avia Page Builder, from the simple margin: 0 auto; to more complex flexbox layouts, but nothing has worked.

Countless hours have been wasted on this simple task and I would greatly appreciate any assistance ??
