要为Bootstrap卡设置容器并将其设置为组，请使用card-group类。
使用它并使用两个Bootstrap卡创建如下所示的网格-
<div class="card-group"> <div class="card bg-primary"> <div class="card-body text-center"> <p class="card-text">Demo Text!</p> </div> </div> <div class="card bg-warning"> <div class="card-body text-center text-white"> <p class="card-text">Warning!</p> </div> </div> </div>
以下是在Bootstrap中创建网格（卡组）的示例-
<!DOCTYPE html> <html lang="en"> <head> <title>Bootstrap Example</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css"> <script src="https://cdn.staticfile.org/jquery/3.3.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script> </head> <body> <div class="container"> <h3>Group of Messages</h3> <div class="card-group"> <div class="card bg-primary"> <div class="card-body text-center"> <p class="card-text">Demo Text!</p> </div> </div> <div class="card bg-warning"> <div class="card-body text-center text-white"> <p class="card-text">Warning!</p> </div> </div> <div class="card bg-success"> <div class="card-body text-center"> <p class="card-text">Well done!</p> </div> </div> <div class="card bg-success"> <div class="card-body text-center"> <p class="card-text">Selected!</p> </div> </div> </div> </div> </body> </html>
