代码如下：

/*分页*/
<div class="pager">{$pages}</div>

1、有间隔CSS样式

/*分页*/
.pager {text-align: center; margin: 20px 0;}
.pager ul {display: flex; flex-wrap: wrap; justify-content: center}
.pager ul li {display: inline-block;}
.pager ul li a {padding: 5px 15px; margin: 15px 5px; border: #dddddd solid 1px; display: inline-block;}
.pager ul li a:hover {border: #3ea8e2 solid 1px; color: #3ea8e2}
.pager ul .active a {border: #3ea8e2 solid 1px; display: inline-block; background-color: #3ea8e2; color: #fff;}
.pager ul a:not([href]):not([class]):hover {border: #dddddd solid 1px;}
.pager ul .active a:hover {color: #fff; border: #3ea8e2 solid 1px !important;}

2、无间隔样式

/*分页*/
.pager {text-align: center; margin: 20px 0;}
.pager ul {display: flex; flex-wrap: wrap; justify-content: center}
.pager ul li {display: inline-block;}
.pager ul li a {padding: 5px 15px; border: #dddddd solid 1px; margin-left: -1px; display: inline-block;}
.pager ul li a:hover {border-color: #70c4f3; background-color: #70c4f3; color: #FFF}
.pager ul .active a {border: #3ea8e2 solid 1px; display: inline-block; background-color: #3ea8e2; color: #fff;}
.pager ul a:not([href]):not([class]):hover {border: #dddddd solid 1px; background-color: #fff}
.pager ul .active a:hover {color: #fff; border: #3ea8e2 solid 1px !important; background-color: #3ea8e2 !important}
