网站结构语义内容标注
2023-08-09 加入收藏
Web标注的语义化是高效Web编码、信息架构、通用可用性、搜索引擎可见性以及最大显示灵活性的核心概念基础。可以通过Web浏览器、各种移动计算设计和屏幕阅读器来访问Web内容。也可以通过搜索引擎以及其他能从HTML标注内容的方式中提取含义和上下文的计算系统来阅读Web内容。
This is the most important headline
This is ordinary paragraph text within the body of the document, where certain words and phrases may be emphasized to mark them as particularly important.
This is a headline of secondary importance to the headline above
Any time you list related things, the items should be marked up in the form of a list:
- A list signals that a group of items are conceptually related to each other
- Lists may be ordered (numbered or alphabetic) or unordered(bulleted items)
- Lists may also be menus or lists of links for navigation1i>
- Cascading style Sheets can make lists look many different ways
即使在上面这个简单的实例中,搜索引擎也能区分标题的重要性和优先级别,发觉哪些 关键字是重要的,并且识别列表中概念上相关的项。专门针对手机设计的层叠样式表可以采用适合小屏幕的字体显示标题和文字,屏幕阅读软件知道在哪以及如何通过暂停或变换语音来向盲人读者传递有关内容结构的信息。
