Then you might start at
https://en.wikipedia.org/wiki/Syntax_highlighting
for a summary.

This appears either to contradict your second statement, or you've
been using a system that *does* provide it. Which? assuming you now
know what syntax highlighting is.
Syntax highlighting is complemented by indentation. Whereas the former
is normally imposed on the source when the editor opens the file,
indentation is normally contained as part of the source code.
The implication is that, for conforming code, the highlighting should
be correct, but the indentation could be absent or completely wrong.
Editors usually have commands to reindent regions of code or the whole
buffer, so perhaps start by doing that.

No idea. I take these things as they come, and then tweak them
(perhaps).
Someone mentioned Python. Don't touch any indentation in Python
programs, because it is meaningful not cosmetic: changing the
indentation is like adding/removing braces in other languages.
