Hello. I'm almost completely ignorant when it comes to coding character sheets, but I really wanted a more streamlined version of the D&D 3.5 character sheet for a personal game. I noticed that the official pathfinder 1e sheet shares a very similar layout to the official 3.5 character sheets, so I went about modifying it. However, I can't for the life of me figure out how to make it darkmode compatible. I eventually just forced it into darkmode by adding an invert filter over everything contained in the html, but there's still a border around the contents of the sheet that I can't invert. Picture provided for context. Any help would be appreciated.
