set left and right margin for all Event Pages

Hello,

it looks like there's not option to edit/adjust the body of the EVENTS function in squarespace.

When looking at these pages on Desktop and Tablet, i'd like the content to be "squeezed" towards the center of the screen, while at the moments, it goes "full" by default and cannot be adjusted at all.

Can someone please help me with the custom code required to make sure that ALL Events pages are left with a decent amount of left and right margin on tablet and desktop?

example page:

i found the solution!
