滑动到可视区域出现动画 WOW.js + animate.css

import React, {Component} from 'react';
import "animate.css";
import { Helmet } from 'react-helmet';
import './home.scss';
import { Modal, Button } from 'antd';
import ReactWOW from 'react-wow';
import { Row, Col } from 'react-bootstrap';
import { AppContainer } from "./components";
import Carousel from "./Carousel";
import Dropdown from 'react-bootstrap/Dropdown';
import DropdownButton from 'react-bootstrap/DropdownButton';
import FooterNav from './components/FooterNav'
import HttpUtils from '../../utils/HttpUtils'
import WOW from 'wowjs';

export default class Home extends Component {
  constructor(props) {
    super(props)
    this.state ={
    }
  }


  componentDidMount() {
    new WOW.WOW().init();
  }

  render() {return (
      <div>
        <div className={'test1'} />

        <div className={'test2'} />
        <div className={'test3'}>
          <section className="wow bounceInUp" data-wow-offset="100" data-wow-duration="0s" data-wow-delay="0.5s">关于我们</section>
          <section className="wow bounceInUp" data-wow-offset="100" >关于我们</section>
        </div>
        <div className={'test4'}>
          <section className="wow bounceInUp" data-wow-offset="100" >关于我们</section>
          <section className="wow bounceInUp" data-wow-offset="100" >关于我们</section>
          <section className="wow bounceInUp" data-wow-offset="100" >关于我们</section></div>
      </div>
    )
  }
}

.test1,.test2,.test3,.test4{
  height: 1000px;
  background-color: rgba(122,122,122,.5);
}

wow.js offset失效问题：

//body, html {
//  overflow-x: hidden;
//}
