Contact Form Issue

We have had a developer we work with look at issues we are having with the contact form and he has said there is an issue in the CSS. Right now, the contact form is only showing up about a 1/3 width of any page it’s on even if it’s set to be full width in the visual composer. I am needing it to show full width of whichever visual composer box we place it in for different pages.

I attached a screen grab where he made a change for it to say “block” for display vs. what it is currently coded as – it wouldn’t stick when he made the change in the front end – knowing it needs to be in the CSS, but it’s in so many places he’s not sure where to make that change. Is this something that can universally be changed for the theme?
