我想让pagination-sm类只应用于小型设备(sm)，但是pagination-sm-sm不能像w-sm-50那样工作，所以我该如何做呢？

我可以想出三种不同的方法来实现这一点：

使用媒体-询问定义自己的自定义类，并手动添加特定屏幕大小的样式。

<html lang="en">

<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">

  <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.2.0-beta1/dist/js/bootstrap.bundle.min.js" integrity="sha384-pprn3073KE6tl6bjs2QrFaJGz5/SUsLqktiwsUTF55Jfv3qYSDhgCecCxMW52nD2" crossorigin="anonymous"></script>
</head>

<body>
  <nav aria-label="Page navigation example">
    <ul class="pagination">
      <li class="page-item"><a class="page-link" href="#">Previous</a></li>
      <li class="page-item"><a class="page-link" href="#">1</a></li>
      <li class="page-item"><a class="page-link" href="#">2</a></li>
      <li class="page-item"><a class="page-link" href="#">3</a></li>
      <li class="page-item"><a class="page-link" href="#">Next</a></li>
    </ul>
  </nav>

  <style>
    @media only screen and (min-width: 576px) and (max-width: 768px) {
      .pagination {
        --bs-pagination-padding-x: 0.5rem;
        --bs-pagination-padding-y: 0.25rem;
        --bs-pagination-font-size: 0.875rem;
        --bs-pagination-border-radius: 0.25rem;
      }
    }
  </style>
</body>

</html>

根据当前的JavaScript对切换类使用窗口大小。

// Toggle class pagination-sm based on window width
function setPaginationSize() {
  var width = window.innerWidth
  var pagination = document.querySelector('.pagination')
  pagination.classList.toggle("pagination-sm", width >= 576 && width < 768)
}

// Initial call to set pagination size on page load
setPaginationSize()

// Call setPaginationSize() on window resize
window.addEventListener('resize', function() {
  setPaginationSize()
});

<html lang="en">

<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">

  <nav aria-label="Page navigation example">
    <ul class="pagination">
      <li class="page-item"><a class="page-link" href="#">Previous</a></li>
      <li class="page-item"><a class="page-link" href="#">1</a></li>
      <li class="page-item"><a class="page-link" href="#">2</a></li>
      <li class="page-item"><a class="page-link" href="#">3</a></li>
      <li class="page-item"><a class="page-link" href="#">Next</a></li>
    </ul>
  </nav>
</body>

</html>

(这款既快又脏，不推荐在生产中使用。)创建分页的副本，并仅在要排除分页的屏幕大小上显示：

<html lang="en">

<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>

<body>
  <nav aria-label="Page navigation example">
    <ul class="pagination pagination-sm d-none d-sm-flex d-md-none">
      <li class="page-item"><a class="page-link" href="#">Previous</a></li>
      <li class="page-item"><a class="page-link" href="#">1</a></li>
      <li class="page-item"><a class="page-link" href="#">2</a></li>
      <li class="page-item"><a class="page-link" href="#">3</a></li>
      <li class="page-item"><a class="page-link" href="#">Next</a></li>
    </ul>
    <ul class="pagination d-flex d-sm-none d-md-flex">
      <li class="page-item"><a class="page-link" href="#">Previous</a></li>
      <li class="page-item"><a class="page-link" href="#">1</a></li>
      <li class="page-item"><a class="page-link" href="#">2</a></li>
      <li class="page-item"><a class="page-link" href="#">3</a></li>
      <li class="page-item"><a class="page-link" href="#">Next</a></li>
    </ul>
  </nav>
</body>

</html>
