Image-set ()

Image-set can ensure the adaptation of images on different resolution devices and display different images according to different device types. See the following example

Background-image:-webkit-image-set (url (. / bg1x.png) 1x, url (. / bg2x.png) 2x)

This example means to display bg1x.png on the 1 x screen and bg2x.png on the 2 x screen. In terms of compatibility, the latest mainstream browsers have already supported it. For devices that are not supported, you can use background:url () to be compatible before using this function.
