I've exhausted all my options. I've attempted to add a certain % page width globally using CSS in the editor, page template, and customizer but it's just not working.
It's frustrating because I'm using the Twenty Twenty Two theme, which is supposed to be the default theme, so I don't understand why it's not cooperating.
This is what I've tried in the page & theme CSS:
.entry-content > *:not(.alignwide):not(.alignfull):not(.alignleft):not(.alignright):not(.is-style-wide) {
max-width: 87rem;
width: calc(100% - 8rem);
}
I also attempted to adjust it directly by turning off inherit default dimensions and inputting a % and pixel manually, but nothing seems to work.
I'm completely baffled at this point.
