先导入的是这个组件自己的样式
后导入的是组件

组件的样式就会覆盖这个组件自己的样式。

import React from "react";

import "./index.css";

import { Route } from "react-router-dom";
import { TabBar } from "antd-mobile";
// 组件
import Index from "../Index/index";
import List from "../List/index";
import News from "../News/index";
import My from "../My/index";
