There is too much whitespace. I need to be able to fit more on one screen on desktop. If anyone has a solution, much appreciated.
You can create a custom subtheme to customize CSS
https://pgorod.github.io/Customize-SubTheme/
Actually that article is not very good (yes, it was written by me…) because those customizations are not upgrade-safe. The changes should be done in the custom directory. But it gives you some pointers about SASS compilation and subthemes structure.
