<style lang="scss" scoped>
.call-center {
  opacity: 0.7;
  color: #000;
   160px;
  //   height: 160px;
  top: 8%;
  right: 2%;
  //   border-radius: 50%;
  position: fixed;
  z-index: 99999;
  text-align: center;
  background: #eeeeee;
  border: 3px solid rgb(216, 194, 194);
  i {
    display: block;
    font-size: 32px;
    margin-top: 16px;
    color: #606266;
    transition: color 0.15s linear;
  }
}
</style>

 应功能需求更新，增加了一个拖拽表单界面的功能。el-dialog的位置由margin-left，margin-top决定（相当于之前的left与top）
