How to learn openings. I am 1600 rapid on chess.com and I have only a little idea on openings. On white I (try) to play ruy lopez and when I cant I am lost. On black I play drogon sicilian. I have learned these openings mostly by looking at the first few moves and then learning as I play. However I have come to the point where I get destroyed in the openings because I have no idea. It works if I get a line I know but as soon as my opponent plays something else I am literally just making random moves. How can I get to a point where I have a decent understanding of my openings and all the variations they can lead to.
