If I’m totally honest, I probably under-use IDs. I think I read somewhere that IDs perform slightly better in terms of speed. BUT… with classes you get re-usability and you’re able to add multiple classes to one element. The former, you shouldn’t do with IDs and correct me if I’m wrong but the latter won’t even work with IDs.
