How to display the background image without adding width or content? _html/css_WEB-ITnose
There is a background with things on the left and right sides. Then when cutting the picture, cut out two small pictures on the left and right sides. Make it adapt to the size of the screen. (But a fixed width must be added to display the background.). How to prevent the background layer from displaying when the screen size is 1024? Because of the width problem, the content in the middle has been moved down. It's normal on a 1440 screen. But when the size is 1024, the content will be moved down. . . well. . I don’t know if I expressed it clearly?
Please let anyone know. . . Thank you~

This should be controlled by js
Yes.
But let me tell you, one big picture is better than two small pictures, because the total bytes of the large background picture are smaller and there is one less http
