1.jpg在HTML5之前采用HTML+CSS文档结构写法

【ID选择器说明 id选择器——用于标识页面上特定元素(比如站点导航、页眉、页脚)而且必须唯一; 也可以用来标识持久结构性元素（如主导航、内容区域）】

【class选择器说明 class类选择器——可以应用于页面任意多个元素，非常适合标识内容类型或其他相似的条目】

缺点 1.不利于SEO搜索引擎对页面内容的抓取

        2.文档结构定义不明确

于是HTML5出现，解决上述问题，专门添加页眉、页脚、导航、文章内容等跟结构相关的结构元素标签

header 页眉, nav 导航, section 区块, article 文章, aside 侧边栏 ,  footer 页脚
