继 js 分号要不要写之后,蛋疼问题第二发。
HTML5 里为了更好的语义化,提供了很多标签,section、article、header、footer、nav、aside、figure 神马的。现在问题来了,原先都是 div 随便写,现在想用上这几个标签,但立马就苦恼了。
section、article 什么区别?
nav 是全站的 nav 头才能用,还是所有的菜单栏都用?
aside 是指侧边栏,还是内容排版时放在旁边的附图、代码之类的容器?
这篇文章说得挺好,给了许多观点,我是赞成它的

回复内容:
给你举个形象的例子。你在 word里打一篇长文章,这篇文章其实就是一篇article。word每一页都有页眉和页脚,这就是header和footer。所以你发现一个文章被word分了好多页,所以他可以有若干个header和footer。再说说nav,你写文章很长划分了好多小标题,左侧出现的那个文章菜单导航路径就可以理解为nav;
最后说下p和section,你写了这么一篇文章肯定分了好多自然段,这些自然段就是p,而整篇文章可能按照其大义分了段(又叫章节,一个章节可能有多个自然段组成)这时候这个分出来的大的段落就叫section。 我觉得HTML 5里面很多标签实际上不是为了布局而设,而是为了表明其中内容的含义。这么做,我个人揣测,是为了将来更便于使用程序从页面中抓取和分析内容 在这里 article ≠ 文章,article = 物件,就好理解了 article@dict.cn 传送门: Semantic HTML by @顾轶灵. 要跳脱开布局来理解这些东西。 其实就是语义化标签,没那么复杂,我的理解:
- section 比article小一级,可以嵌套
- article 正文
- header 页眉
- footer 页脚
- nav 导航栏(横的竖的都行)
- aside 正文里的图片、注解
- figure 表格
