This hit a nerve as I am in the middle of developing a webapp for myself using NiceGUI. I find CSS, especially its layout framework, pretty confusing and sometimes downright intimidating to work with. `inline`, `block`, `flex`, `grid` seem reasonable when you read about them. But when using it, especially within frameworks when flexboxes are nested within grids which are nested within flexboxes and so on, it becomes hard to reason about. And then you throw in media-queries in the mix and it becomes even more dense.
