问题描述
这是我的代码：
<html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous"> <style> #gg{ display:none; } video { transform: scale(-1, 1); object-fit: cover; } </style> <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script> <script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js" integrity="sha384-OgVRvuATP1z7JjHLkuOU7Xw704+h835Lr+6QL9UvYjZE3Ipu6Tp75j7Bh/kR0JKI" crossorigin="anonymous"></script> </head> <body class="p-1"> <div class="border-top border-primary container-fluid d-flex flex-column"> <div class="row"> <div class="border-left border-bottom border-primary col-6 h4 p-1 mb-0"> Self View </div> <div class="border-left border-bottom border-right border-primary col-6 h4 p-1 mb-0"> Remote View </div> </div> <div class="row"> <div class="border-left border-bottom border-primary col-6 p-1"> <div class="card text-white"> <video id="selfView" autoplay muted class="card-img" style="max-height:25vh;height:auto"> <source src="https://www.w3schools.com/html/mov_bbb.mp4" type="video/mp4"> </video> <div class="align-items-center bg-secondary card-footer d-flex flex-row h4 justify-content-between mb-0 p-1"> <div class="muteBtn">🔇<span class="elapseTime"></span></div> <div class="minMaxBtn">⛶</div> </div> </div> </div> <div class="border-left border-bottom border-primary border-right col-6 p-1"> </div> </div> </body> </html>
我想实现媒体播放器的最大化function。 所以，我想知道如何让卡片组件全屏显示。
我尝试执行以下操作，但不起作用：
- 将 h-100,w-100 class 添加到卡组件
- 将 card-fullscreen class 添加到卡片组件
除此之外，面板组件已从 Bootstrap 4 中删除。因此，我无法使用面板组件。

您可以在下面查看 class 全屏。 我在按钮上使用简单的 onclick function 实现您的代码，使其全屏显示，第二次单击它将恢复正常。

最后，我完成了。
