我是 bootstrap 的初学者，我尝试放置一个指向我的 css 文件的链接，但它不起作用。由于我不是程序员，只是为了学校做这件事，所以我不知道所有正确的做事方式......

为了检查是否一切正常，我尝试在文档中输入一个词并为其设置样式，但未显示样式。

这可能是链接的问题，或者我还不了解 bootstrap，但我无法自行解决。

最佳答案

我试过你的代码它适用于我必须确保文件 stylesheet.css 与你的 index.html 文件位于同一文件夹中

elseif 这是我的代码都在 index.html 中

<!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>

  <body>
  <nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="#">Stefan</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav ">
      <li class="nav-item ">
        <a class="nav-link" href="#">Over</a>
      </li>
      <li class="nav-item">
