Arguably they should all be in external files. HTML in one, CSS in another, and Javascript to load and cache them without any embedded strings. That's how I prefer to write. For one thing, it lets me choose which things I want to cache and which I don't. I can compile from SCSS and deploy without changing any JS or HTML files. Usually my rollups are just the JS.
