Make site text inline with full-width navigation

Hi there - a client is requesting that the text throughout the website be aligned with the full-width navigation. I attached screenshots.

Is there some way to add custom code to do this? Seems like I'm limited with fluid engine unless I want the text to extend all the way to the edge - which I do not want.

Thinking I might have to make the navigation inset in order to make everything aligned - however the client requested the text be closer to the edge of the screen like the navigation is 😕

Any insight is appreciated!

A full-width header just has the site padding left and right of it, if you wanted to do this with the content of your website you would need to make the content width 100%, you can set that in the Styles -> Spacing menu, but I would suggest being careful with your design as on large screens it will look quite different.

My guess is that your client will be happy enough if it looks right to them, so maybe pick a max site width that matches their screen size.
