when watching the js game engine, there is a situation of automatic horizontal screen and automatic vertical screen. When the mobile end develops a mobile page similar to a game (there is no need to use the game engine), the game page design is likely to be in full screen mode. If the user sets a screen lock and does not allow screen rotation, the page should be full of full screen when opened, forcing the page to rotate 90 degrees. Is there a good plan? Rotate the page 90 degrees and rotate all the elements in it?
