一、标题
标题的h1到h6标签，这里不再赘述。值得一提的是，H5中新定义了一个元素，用来将标题和副标题群组。一般在header里将一组标题组合在一起，变成一个区块：
1 <body> 2 <header> 3 <hgroup> 4 <h1 id="阿里旅行-middot-去啊"> 阿里旅行·去啊 </h1> 5 <h2 id="阿里旅行-middot-去啊是阿里巴巴旗下的综合性旅游出行服务平台"> 阿里旅行·去啊是阿里巴巴旗下的综合性旅游出行服务平台 </h2> 6 <p>阿里旅行·去啊，世界触手可行</p> 7 </hgroup> 8 </header> 9 <article>10 阿里旅行·去啊整合数千家机票代理商、航空公司、旅行社、旅行代理商资源，直签酒店，客栈卖家等为广大旅游者提供特价机票，酒店预订，客栈查询，国内外度假信息，门票购买，签证代理，旅游卡券，租车，邮轮等旅游产品的信息搜索，购买及售后服务。全程采用支付宝担保交易，安全、可靠、有保证。11 </article>12 <body>13 </body>
二、关键字和产品名称
标签包裹的部分比其余部分更重要，呈现为粗体。以下场景可以使用b标签：文档的摘要中的关键字；产品描述中的产品名；其他文本在需要加粗显示的情况下。
根据H5规范，再没有其他更合适的标签时，才把b作为最后的选项。H5声明用h1到h6表示标题，em表示要强调的文本，strong来表示重要文本，mark表示标注的、突出显示的文本。
三、强调
标签表示强调其中的文本，用斜体来显示。但是如果只是单纯的想要斜体效果，请使用i标签。
四、外文或科技术语
标签也是显示斜体效果，使用场景为：表示转述句；表示分类名称；习语。
五、重要文字
和一样用于强调文本，但它强调的程度更强一些。显示效果为加粗。
六、删除线
显示效果为删除线，可以和标签配合使用。H5中的删除线用 。
七、下划线
可以在css样式属性中的text-decoration设置为underline来为文字添加下划线，也可以利用u标签设置。在H5中不再支持u标签。如果不是超链接的话不建议添加下划线。
八、小号字体内容
