跟随鼠标3D倾斜

1. 创建一个vanilla-tilt.js文件
2. 将一下代码黏贴进去

3. export var VanillaTilt = (function () {
     'use strict';

       }
     }
   
     if (typeof document !== "undefined") {
       /* expose the class to window */
       window.VanillaTilt = VanillaTilt;
   
       /**
        * Auto load
        */
       VanillaTilt.init(document.querySelectorAll("[data-tilt]"));
     }
   
     return VanillaTilt;
   
   }());
   

   使用：

   VanillaTilt.init(document.querySelectorAll('.publicize-item'), {
         max: 15, //最大倾斜度数
         speed: 400, //倾斜转换的速度
         glare: true, //是否开启眩光效果
         'max-glare': 1, //最大眩光的不透明度
         scale: 1.05 //指定2D旋转的缩放
       });
