Is it best practices to split an index file into three files for html, css and JavaScript?

I don't think Astro supports it but I may be 100% wrong bc I hardly know what I'm doing

It depends a little bit on what kind of set up you're working in but generally I would split those out into individual files, yes.

It depends and is personal preference to a big extent

Using Astro it’s most common to colocate everything in one file and split into multiple components if it’s getting too big
