  <p style="white-space:pre">
    Bid me discourse, I will enchant thine ear, Or like a fairy trip upon the
    green, Or, like a nymph, with long dishevell'd hair, Dance on the sands, and
    yet no footing seen: Love is a spirit all compact of fire, Not gross to
    sink, but light, and will aspire.

HTML5 结构化元素

标签	作用
header	body、main 标签的直接子标签，位置在页面头部，内容可能为 logo、标语、搜索提示、导航栏
nav	导航栏包在 nav 标签内，可能出现在头部、侧边栏、底部等等，神奇的地方在于设置 nav 标签的 display:inline-block，是作用在 li 标签上的
main	body 标签的直接子标签，主内容区域
aside	侧边栏
article	一般出现在 main 标签内，article 标签内可以有 section、footer 等标签，是比较独立的内容，比如像博客网站主页的一个文章简介
section	section 和 div 很类似，如果使用 div 标签是为了对内容做样式控制，或者为了便于 javascript 获取做其他操作，那么使用 div 就是你的答案，其他情况就用 section
address	提供联系信息，放在 article 标签内提供文章作者信息，放在 main、body、footer 内提供网站信息
footer	一般在 HTML 结构底部，补充网站信息，如果放在 article 内补充文章信息
