the CSS fonts spec has a couple (new to me) generic font families, like ui-serif and ui-sans-serif, aimed at providing finer-grained controls for specifying OS-level fonts. This allows developers the power to integrate their UIs with the look and feel of the underlying operating system.

BEM — Block Element Modifier is a methodology that helps you to create reusable components and code sharing in front-end development.
BEM is a highly useful, powerful, and simple naming convention that makes your front-end code easier to read and understand, easier to work with, easier to scale, more robust and explicit, and a lot more strict.
The BEM approach ensures that everyone who participates in the development of a website works with a single codebase and speaks the same language. Using BEM’s proper naming convention will better prepare you for design changes made to your website.
