在Bootstrap 4卡中的标题后设置字幕
要在Bootstrap卡中的标题后设置字幕，请使用卡字幕类。
让我们看看如何-
<h6 class="card-subtitle text-muted"> Set Subtitle here </h6>
在card-title类之后和card-body类内部添加以上内容-
<div class="card-body"> <h4 class="card-title">Sports</h4> <h6 class="card-subtitle text-muted">Indoor</h6> <p class="card-text">Squash, Dart, Chess</p> </div>
您可以尝试运行以下代码以在Bootstrap卡中设置字幕-
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">
