# 1. 谷歌浏览器

添加自定义 class

<el-checkbox-group v-model="checkList">
             <el-checkbox class="checkbox"></el-checkbox>
</el-checkbox-group>
.checkbox{
    zoom: 200%;
}

如果发现有浏览器没有作用那就用下面的办法

# 2. 其他浏览器

/deep/.el-checkbox__inner {
    width: 19px;
    height: 19px;
  }
/deep/.el-checkbox__inner::after {
border: 1px solid #fff;
border-left: 0;
border-top: 0;
left: 7px;
top: 4px;
}
/deep/.el-checkbox__input.is-checked .el-checkbox__inner::after {
transform: rotate(50deg) scaleY(1.5);
}
