I don't quite understand the relationship between px, pixels, resolution.

recently I am learning mobile development, which involves these contents.

it seems that there may be 1-3 pixels on 1 px

those who want to understand, please tell me, thank you!

in fact, this is not just a matter of pixels and resolution. You have to figure out CSS pixels, physical pixels, logical pixels, device pixel ratio, PPI, Viewport, and understand these knowledge points together before you can form a concept. Some predecessors have summed it up, and I will lend flowers to offer Buddha here. It is recommended to read this article
