Take a few common openings, like the Italian and Queen's Gambit for White and the Petrov and Indian for Black, and look up a video or an article of someone explaining the ideas.
Gothamchess has some 10-minute tutorials on various openings. Not a fan of him as a person or YouTuber most of the time but his tutorials are smack.
Gotham chess is a choice for basic lessons IMO. I don’t recommend trying to learn too many openings at the same time. I used go over master games instead of just studying books. Also Chessable has a feature helping to learn openings by repetition. Some of their courses are free.
Play over GM games until you find an opening whose structure and piece play inspires you. Then start playing it. What I try to do to learn it is: make a notebook [by hand] with the main variations, play over LOTS of GM games with the opening-full games- looking at ideas, strategies and tactics. I find I start to understand after about the first 100. Along the way I keep a book of tactic problems based on combinations in the games I play over and I review it as puzzles periodically. After that I go back to my notebook and start writing in word-stories explaining the moves. After that I play over more GM games and try to add my own annotations.
Chessable had free courses an paid ones. I play less games now an focus more on chessable.
Learning by teaching is working out for me. My original plan was to make videos that teach openings, figuring that under that much pressure, the learning becomes obsessive. Writing it out has turned out to be a better way, along with simple screenshots. In fact, just naming the images and files, then writing out links to them, it's hard to forget 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 (Morphy Defense). It'll just take about a year to make a page for each move. :-)

I'm trying to improve but I feel stuck when it comes to exploring new openings. Do you guys have any tips?
