组件如下，
1. 为了提高 selector 优先级，可以链接多个class，例如：
.page-link.page-link-current {
}
2. 取消 button 的默认灰色背景色：
background: none;
3. button 和 a 默认都是 inline,
4. a 里加 padding，不能保证它们是正方形，但是，通过设置 inline-block，并且设置相同的宽和高，于是就可以。
5. 默认情况下，flex 容器也是一个 block 元素
设置
a {
display: flex;
}
于是，所有的 a 都变成了 block 级元素，于是它们产生换行，从上到下叠加到一起。
6. .pagination 容器并没有设置 width 和 height
代码如下：
