Tips for Improving Opening Skills?

I'm looking to improve my opening repertoire and was wondering where the best place is to learn more advanced openings. I’m pretty comfortable with the basics like e4 and d4, but I’d like to dive deeper into different openings and strategies. Any suggestions on great resources or platforms for learning and practicing these would be really appreciated.

The practice options on Chess.com don’t seem to be helping much.

What opening do you play at the moment?

If want to improve opening then practice, practice and practice

Yeah, I get that practice is important, but I’m not sure how to actually start learning a new opening.

Watching Hanging pawns videos on youtube is how I learned. He's got introductory videos on pretty much every opening. The analysis board on lichess also will tell you move percentages in different positions, which lets you know what to study.

Before building a comprehensive repertoire it's good to at least have a broad view of the different openings and understand the basic ideas in most of them. That doesn't mean you have to know them deeply, but it doesn't take very long to get acquainted with the position on a very basic level and understand the basic ideas... like 10 minutes watching a hanging pawns video. Then you'll know what you're doing when building your repertoire... when you transpose into one position or another you'll have some idea of what position it is, what its relevance is, what the plan may be... and to get good at the opening the first step is choosing the right one for your purposes, and you can't really do that if you have no idea what's available.

Thanks, my biggest issue is not really knowing which openings are out there or what people usually play against them. So I’m kinda stuck on where to begin. I guess I need to explore a bit more first and get a feel for what’s common, then start learning the different lines

If you want to invest a little bit to buying a book, I would recommend Fundamental Chess Openings by Paul van der Sterren. It contains the basics of all major openings and a little bit of the less played ones, too. It explains ideas behind the first 5-10 moves per opening. It is ideally suited for people in the rating range 1000-1600 or so and since it doesn't go deep in any lines, it will not be outdated easily. On the other hand it does not discuss the transition to middlegame, so for that you will need something else. Another thing is that it does not put much emphasis on system openings or opening traps, which some people tend to use.
Besides learning the elements of various openings, reading the book makes following chess more enjoyable as you will understand what the commentary is about.

Did the OP ever say what openings they are playing?

I mean the best way to learn openings is holistically. Don't go looking for openings, instead, play your usual every game, and at the end of every game, analyze your game and add one move to your opening. For example,

My games usually start with the Giuoco Piano.
