Bootstrap5 分页
网页开发过程，如果碰到内容过多，一般都会做分页处理。
Bootstrap 5 可以很简单的实现分页效果。
要创建一个基本的分页可以在 <ul> 元素上添加 .pagination 类。然后在 <li> 元素上添加 .page-item 类，<li> 元素的 <a> 标签上添加 .page-link 类:
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap5 实例</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<div class="container mt-3">
<h2>分页</h2>
<p>要创建一个基本的分页可以在 ul 元素上添加 .pagination 类。然后在 li 元素上添加 .page-item 类：</p>
<ul class="pagination">
<li class="page-item"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item"><a class="page-link" href="#">Next</a></li>
</ul>
</div>
</body>
</html>当前页页码状态
当前页可以使用 .active 类来高亮显示：
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap5 实例</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<div class="container mt-3">
<h2>当前页页码状态</h2>
<p>当前页可以使用 .active 类来高亮显示：</p>
<ul class="pagination">
<li class="page-item"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item active"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item"><a class="page-link" href="#">Next</a></li>
</ul>
</div>
</body>
</html>不可点击的分页链接
.disabled 类可以设置分页链接不可点击:
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap5 实例</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<div class="container mt-3">
<h2>不可点击的分页链接</h2>
<p>.disabled 类可以设置分页链接不可点击:</p>
<ul class="pagination">
<li class="page-item disabled"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item"><a class="page-link" href="#">Next</a></li>
</ul>
</div>
</body>
</html>分页显示大小
可以将分页条目设置为不同的大小。
.pagination-lg 类设置大字体的分页条目，.pagination-sm 类设置小字体的分页条目:
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap5 实例</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<div class="container mt-3">
<h2>分页显示大小</h2>
<p>.pagination-lg 类设置大字体的分页条目，.pagination-sm 类设置小字体的分页条目:</p>
<p>大:</p>
<ul class="pagination pagination-lg">
<li class="page-item"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item"><a class="page-link" href="#">Next</a></li>
</ul>
<p>默认:</p>
<ul class="pagination">
<li class="page-item"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item"><a class="page-link" href="#">Next</a></li>
</ul>
<p>小:</p>
<ul class="pagination pagination-sm">
<li class="page-item"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item"><a class="page-link" href="#">Next</a></li>
</ul>
</div>
