Question

我是使用Bootstrap的初学者，我尝试将链接放置到我的CSS文件中，但是它不起作用。由于不是程序员，只是在学校读书，所以我不知道所有正确的做事方式...

要检查一切是否正常，我尝试在文档中放置一个单词并设置样式，但是样式没有显示。

链接可能有问题，或者我还不了解引导程序，但我无法自行解决。

#hi{
      font-size: 75px;
      color: red;
}

我尝试过对您有用的代码，但必须确保stylesheet.css文件与index.html文件位于同一文件夹中

否则，这是我所有在index.html中的代码

<!doctype html>
<html lang="en">
  <head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <!-- Bootstrap CSS -->
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
    <style>
    #hi{
      font-size: 75px;
      color: red;
    }
    </style>
    <link rel="shortcut icon" href="icons8-s-100.png" />
    <title>Stefan Kloosterman</title>
  </head>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">

由于引导程序而没有显示CSS样式？
