Don’t understand how this page is made? When the browser window is zoomed, the content inside will also zoom. Once the zoom reaches a certain level, it will no longer zoom.

How do you do it?

This should be composed of many divs. When the mouse is pulled to the left, the mouse position is recorded, and then the div is dragged to the mouse Location! This makes it look like a mobile phone. Besides, this itself is the official website of a mobile phone! , which is actually useless!

It’s very simple, you can do it with CSS instead of JS. Just search for articles on the use of "CSS relative length units".
