Image Block full width without impacting any other content/blocks

Site URL: https://rose-kazoo-fasw.squarespace.com/config/pages

Hello,

I am hoping to find a code that can be applied to all pages that will make the highlight blue banner image block to be full width and remove padding from the menu, but WITHOUT impacting the blocks below, which I wish to remain constrained by the template.

Thanks, DL
