The main way to extend Plasmic is to use your own React code components. So if there's something you can't achieve with our editor, you can make a component that does it, and use it in the design. An alternative way is to use the Plasmic components that we generate, which expose a lot of hooks that lets you instrument the props and rendered content within the component, without having to edit the generated component code itself. It is our explicit goal that you never need to edit the Plasmic-generated code in order to extend it to do what you want.

As for the actually generated code, it basically maps to what you've created yourself in the studio. Plasmic does have a styling / element abstraction, but it's fairly low-level, and everything is pretty close to how you'd write a React component yourself. If you're not creating empty divs in the editor, you shouldn't see empty divs in the generated code :-)
