I did both, separated is my way to go. Having both separated makes things easier and cleaner IMHO. You can have a designer to create these seperated layouts, which is pretty cool when you’re a UI/UX designer. The ability to reuse the same code with a different UI layout. And of course generates less conflicts on Git when someone worked on the code while you where on the UI.
