I’ve tried various different custom CSS codes but none of them seem to work. I simply need to reduce the left and right margins by about 50% across my whole website. If there’s a way to also move the right sidebar out of the way too that would be great.
Now that said, this isn’t a problem on mobile – but there is clearly excessive whitespace on desktop view that is just stubborn.
