we should make the .float-root use

display : grid; 
place-items : center;

And then have .b-centered use

position : static;
align-self : auto;

That way, they would just be centered by layout, without that top : 50%; left : 50%; transform : translate(-50%, -50%); hack. No visible difference, just cleaner modern CSS.
