How to change the background in vscode

"background.customImages": [
    "file:///D:/独角兽.jpg"
  ],
  "background.style": {
    "content": "''",
    "pointer-events": "none",
    "position": "absolute", //图片位置
    "width": "100%",
    "height": "100%",
    "z-index": "99999",
    "background.repeat": "no-repeat",
    "background-size": "100%,100%", //图片大小
    "opacity": 0.05 //透明度
  },
  "background.useFront": true,
  "background.useDefault": false  //这里如果为true，则自己设置的图片不起作用，改为false,图片才能出来哦
