When the H5 page of Android phone pops up on the keyboard, the background is compressed. How to solve it?

$("-sharpmobile,-sharprealName,-sharpmobile").on("focus", function() {
    var _this = this;
    setTimeout(function(){
      _this.scrollIntoView(true);
    },200);

but another problem arises, the background image is compressed and deformed, how to solve it? I have tried several methods on the Internet, but none of them work, as shown in the following figure
