使用Bootstrap使元素不可见
要使元素在Bootstrap中不可见，请使用invisible 类。
您可以尝试运行以下代码来隐藏元素-
示例
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap Example</title>
<link href = "/bootstrap/css/bootstrap.min.css" rel = "stylesheet">
<script src = "/scripts/jquery.min.js"></script>
<script src = "/bootstrap/js/bootstrap.min.js"></script>
</head>
<body>
<div class = "container">
<h2>Cricket Boards</h2>
<p>The <abbr title = "International Cricket Council">ICC</abbr> governs cricket boards.</p>
<p class = "invisible">BCCI is also governed by ICC. (This element is invisible)</p>
</div>
</body>
