如何在组件React中注入CSS

问题描述

我已经将一个html文件转换为一个7段LED组件，我从index.css导入了css文件，但是自index.css以来我不知道如何注入样式

I've converted a html file to a component is a 7 segment LED, I imported the css file from index.css, but I don't know how inject the styles since index.css

我试图通过值来注入样式，但是css语法发生了变化，并且组件无法识别
我想知道是否存在一种无需修改即可传递样式的方法css文件

I tried to inject the styles by means of values, but the css syntax changes and the component does not recognizeI want to know if there is a way to pass the styles without modifying the css file

import React from 'react'
import styles from './index.css'

const Display = () =>{
  return(
    <div id="vertical-center">
        <div id="clock-container">
            <div id="display-1" className="display-container display-size-12 display-no-0">
                <div className="segment-x segment-a"><span className="segment-border"></span></div>
                <div className="segment-y segment-b"><span className="segment-border"></span></div>
                <div className="segment-y segment-c"><span className="segment-border"></span></div>
                <div className="segment-x segment-d"><span className="segment-border"></span></div>
                <div className="segment-y segment-e"><span className="segment-border"></span></div>
                <div className="segment-y segment-f"><span className="segment-border"></span></div>
                <div className="segment-x segment-g"><span className="segment-border"></span></div>
            </div>
        </div>
    </div>
  )
}
