CSS is not an art thing. It's just a configuration language with a accidental hierarchical features attached. CSS has as much to do with design as a tube of paint has with painting. As a technology, like all things related to how browsers work really, CSS is not really a well designed part of a wholesome and complete architecture, but an accidental feature on top of a pile of an accidental agglomeration of features. CSS is not art. It's just accidental complexity. It's totally understandable to me if it seems weird. But if you need to learn it - maybe train yourself by small examples? Maybe you are trying to understand the layout of a complete and complex page? What if you implemented simple HTML pages by hand of increasing complexity and figure how CSS affects those? People are different learners but this sort of thing helps me along often. And the font thing - typography has a long history. Since the chances are fairly good that your designer counterparts are font afficionados it never hurts politically to familiarize oneself at least with the history of the craft and to identify serif fonts from sans serif ones. https://en.m.wikipedia.org/wiki/Serif https://en.m.wikipedia.org/wiki/Serif https://en.m.wikipedia.org/wiki/Sans-serif https://en.m.wikipedia.org/wiki/Sans-serif https://en.m.wikipedia.org/wiki/Typography https://en.m.wikipedia.org/wiki/Typography
