How to get content to take up full screen witdth

hello, im new to glide and trying to see if their is a way to get content to take up the full screen width, i have a lot of space on either side of content. I have used all 3 base layouts and wanted to get a layout with 30px padding

I expect that to be only possible with CSS, but then you might have to dive in to adjust a bunch of stuff for different components.
