对于Bootstrap中的有序列表，您可以尝试运行以下代码-
<!DOCTYPE html> <html> <head> <title>Bootstrap lists</title> <meta name = "viewport" content = "width=device-width, initial-scale = 1"> <link rel = "stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css"> <script src = "https://cdn.staticfile.org/jquery/3.3.1/jquery.min.js"></script> <script src = "https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script> </head> <body> <h1>Lists</h1> <h2>Fruits (Ordered List)</h2> <ol> <li>Kiwi</li> <li>Apple</li> <li>Mango</li> </ol> </body> </html>
