No, much longer. I refactored the CSS to accommodate a night theme fueled by only theme color changes (that's to say in the theme admin tabs). You have to change a ton of hard-coded calls into one of a selection of set tints/colours set in the theme admin. You also have to figure out which elements to invert and which ones should not. It was a lot of work! It would be good to have the default theme be easily switchable like that but it's not a small job. I also converted all pixel calls to rem. That was comparatively easy 🙂
