It's crucial to account properly for relationships between components. The best approach to this I've encountered in over 20 years of web-related experience is found at https://every-layout.dev https://every-layout.dev. Compose complex, responsive layouts from expertly crafted primitives, using axiomatic CSS, and positioning becomes a breeze. The non-layout-related styling can be handled however you like; my preference is emotion for component-scoped styles (`sx` prop and styledcomponent API FTW), and design tokens for colors and typographic scale. I've been meaning to write up my approach bc it's exciting to be freed (and free others) from fighting endless css battles.
