theme container width

[sabakParticipant]

hey

i want to increase the container width from pix settings but its fix to 1300px.

i want the container of my site more wider than 1300px.

i tried changing it in additional css but im stuck.

(ive just stretched the row but its not looking good, and the container  width is too smaller for me)
