使一个元素在另一个元素内绝对居中,可以通过绝对定位和margin:auto;的方式
.center_xy{
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    margin: auto;
}
如何使元素内容滚动:
  overflow:auto;

锚点:
  <a>标签的锚点可以和id绑定,<a href="#id">跳转到锚点所在的元素,#代表当前页面

防止class名起冲突:
  在命名时加上外部的class名

设置最小宽度,以便容器内容为空时可显示默认宽度,内容较多时自动扩展
