解决方案

将您的背景更改为设置为body而不是html：

 <!doctype html>
        <html lang="fr">

            <head>
                <meta charset="utf-8">
                <meta name="viewport" content="width=device-width, initial-scale=1">
                <meta name="description" content="">
                <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta2/dist/css/bootstrap.min.css" rel="stylesheet"
                integrity="sha384-BmbxuPwQa2lc/FVzBcNJ7UAyJxM6wuqIj61tLrc4wSX0szH/Ev+nYRRuWlolflfl" crossorigin="anonymous">
            </head>

            <style type="text/css">
                @media (min-width: 768px) {
                    body{
                        background-image: url('https://static.lpnt.fr/images/2017/08/17/9763596lpw-9763750-article-melbourne-jpg_4493712_660x281.jpg');
                        background-repeat: no-repeat;
                        background-size: 100%;
                    }
                }
            </style>

            <body>
                <div class="container" style="background-color: transparent;">
                    <main style="background-color: transparent;">

                            <div class="card mx-auto" style="width: 18rem; margin-top: 25%; background-color: red">                     
                                <div class="card-body" >                            
                                    <h6 class="card-title text-center">Connexion</h6>
                                    <div class="form-group">
                                        <label for="exampleInputEmail1">Email</label>
                                        <input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp">

                                    <div class="text-center">
                                        <a class="btn btn-primary" href="index.html">Se connecter</a>
                                    </div>
                                 </div>
                            </div>
                        </div>
                    </main>
                </div>
            </body>

        </html>
