样式化的组件-为什么动画不起作用？

Question

我们无法使该示例在React中使用样式化组件来工作。

为什么动画在我们的代码中不起作用？我无法让它动起来，不得不求助于使用普通的CSS来获得成功。在某个地方一定是一个简单的错误

import React from 'react'
import styled, { keyframes } from 'styled-components'
import './ticker.css'





export default function Ticker({ text }) {
      return (<div class="ticker-wrap">
        <div class="ticker">
          <div class="ticker__item">Letterpress chambray brunch.</div>
          <div class="ticker__item">Vice mlkshk crucifix beard chillwave meditation hoodie asymmetrical Helvetica.</div>
          <div class="ticker__item">Ugh PBR&B kale chips Echo Park.</div>
          <div class="ticker__item">Gluten-free mumblecore chambray mixtape food truck. </div>
        </div>
      </div>)
    }


 @-webkit-keyframes ticker {
     0% {
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
    visibility: visible;
    }
     100% {
    -webkit-transform: translate3d(-100%, 0, 0);
    transform: translate3d(-100%, 0, 0);
    }
}
 @keyframes ticker {
     0% {
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
    visibility: visible;
    }
     100% {
    -webkit-transform: translate3d(-100%, 0, 0);
    transform: translate3d(-100%, 0, 0);
    }
}
