This week I am refreshing my front-end skills, so I did a little market research. The best resource on CSS basics, I have found, is https://web.dev/learn/css https://web.dev/learn/css. It includes flexbox and grid. For design guidelines I recommend Refactoring UI. It is full of actionable advice, which books such as The UX book is lacking. In my project I use TailwindCSS (by the author of Refacturing UI) with Daisy UI components, so I don't actually write raw CSS. At first TailwindCSS feels like a step backwards to inline CSS, but it is just better than the alternative. I recommend giving it a chance.
