        <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">  
        <title>排版</title>
        <link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/css/bootstrap.min.css">
    </head>
    <body>
         
         
         <div class="row mt-3">
             <div class="col-md-8 p-3 d-flex justify-content-center bg-primary col-12">8</div>
            <div class="col-md-4 p-3 d-flex justify-content-center bg-success col-6">4</div>
         </div>
         <div class="row mt-3">
             <div class="col-md-4 p-3 d-flex justify-content-center bg-primary col-6">4</div>

            <div class="col-md-4 p-3 d-flex justify-content-center bg-danger col-6 offset-3 offset-md-0">4</div>
         </div>
         <div class="row mt-3">
             <div class="col-md-6 p-3 d-flex justify-content-center bg-primary col-6">6</div>
             <div class="col-md-6 p-3 d-flex justify-content-center bg-success col-6">6</div>
         </div>
         

        <script src="https://cdn.staticfile.org/jquery/3.2.1/jquery.min.js"></script>
        <script src="https://cdn.staticfile.org/popper.js/1.15.0/umd/popper.min.js"></script>
        <script src="https://cdn.staticfile.org/twitter-bootstrap/4.3.1/js/bootstrap.min.js"></script>
    </body>
