I was wondering why in some cases just the #id is used, but in some other cases tag#id is used. It makes sense to me for classes since you can have multiple classes in a page, but not for ids. It’s probably a beginner’s question, but that’s what I am. :D
To take it further, sometimes I see things like this:
body#pagewrap ul#nav li.contact a
Why not start that from the li or ul if needed?
These things are still kinda confusing for me, but I’m getting there in my CSS journey.

I think it’s mostly used to up the specificity rating of the selector. You get one extra bonus specificity point for declaring the tag as well. The difference between tag#id and #id is pretty negligible, but the difference between .nav-link and div#menu ul li a.nav-link is pretty huge as far as a difference in specificity value. Say you have a style for .nav-link and you have a style for div#menu ul li a. Then in your HTML, you have:
Ok, that makes total sense. It’s all about the specificity. I think it was just throwing me off sometimes seeing declarations with a bunch of tags, and looking over their whole document they didn’t need to go that far. Maybe they’re being specific for future changes, who knows.
