我正在学习reaction和nextjs,并且面临一个问题,其中引导的css覆盖了我自己的css。
以下是我的代码
Index.js

import Head from "next/head";
import Navbar from "../components/PrimaryBtn";

export default () => (
<div>
<Head>
  <title>Testing</title>
  <meta name="viewport" content="initial-scale=1.0, width=device-width" />
  <link
    rel="stylesheet"
    href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css"
    integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO"
    crossorigin="anonymous"
  />
  <script
    src="https://code.jquery.com/jquery-3.3.1.slim.min.js"
    integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo"
    crossorigin="anonymous"
  />
  <script
    src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js"
    integrity="sha384-ZMP7rVo3mIykV+2+9J3UJ46jBk0WLaUAdn689aCwoqbBJiSnjAK/l8WvCWPIPm49"
    crossorigin="anonymous"
  />
  <script
    src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"
    integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy"
    crossorigin="anonymous"
  />
</Head>
<PrimaryBtn color="blue">click<PrimaryBtn />
</div>
);

PrimaryBtn.js

import React from 'react';
import styles from './PrimaryBtn.css';

export default const PrimaryBtn = (props) => {
return (
<div>
<button className={`btn btn-primary ${styles[props.color]}`}>{props.children}</button>
</div>
);
}

PrimaryBtn.css

.blue {
    background-color: blue;
}

这个背景色被Bootstrap类覆盖,因为Bootstrap CDN是在我的样式之后呈现的。有什么办法可以解决这个问题吗?

如果将console.log(styles)放在PrimaryBtn呈现函数中,我假设您会看到nullundefined。JAVASCRIPT不能理解css,将它导入到您的JAVASCRIPT代码中只是为了确保webpack(或类似的人)将它包含在您的捆绑包中。你只需要在你的className中包括你的班名,我相信className={btn btn-primary ${props.color}}就是你要找的。

我也面临着同样的问题。我通过更改引导的导入来修复它。我没有导入这个:import "bootstrap/dist/css/bootstrap.css";,而是在_app.js的头部导入了Bootsrap CSS,如下所示:

<Head>
    <link
      href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css"
      rel="stylesheet"
      integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC"
      crossorigin="anonymous"
    />
  </Head>
