		placeholder="请输入原登录密码"
		:rules="[{ required: true, message: '请输入原密码' }]"

	<div style="margin: 16px;">
	    <van-button class="repwdBtn" round block type="info" native-type="submit">确定</van-button>
    </div>
</van-form>

@import 'vant/lib/index.css'

这个是在App.vue里面引入的，样式的话根据自己的项目添加，主要是引入css文件

运行

这是全局样式，如果要修改样式，可以重新起类名写样式

message里面信息也可以删掉
