HTML（Hypertext Markup Language）是一种用于创建网页的标准标记语言。在HTML中，标签（tag）是一种用于将内容组织和描述的元素。每个标签都由尖括号（< >）包围，并且通常成对出现，包括一个开始标签和一个结束标签。开始标签和结束标签之间的内容即是标签的作用范围。
下面是一些常用的HTML标签及其作用：
1. ``：定义HTML文档的根元素。
2. `
`：用于包含HTML文档的元信息，如标题、引用的样式表和脚本等。
3. `
`：定义网页的标题，在浏览器的标签页上显示。<p>4. `<body>`：包含网页的主要内容。<p>5. `<h1>`到`<h6>`：定义网页的标题级别，从最高到最低，依次减小。<p>6. `<p>`：定义段落，用于对文本进行分段。<p>7. `<a href="https://www.yihanseo.com/index.php/addons/cms/go/index.html?id=35" target="_blank">JavaScript</a>：一种用于添加交互和动态功能的编程语言。通过<a href="https://www.yihanseo.com/index.php/addons/cms/go/index.html?id=35" target="_blank">JavaScript</a>，可以在网页上执行各种动作和操作。<p>3. SEO（Search Engine Optimization）：优化网页以提高在搜索引擎中的排名和可见性。了解如何编写SEO友好的HTML代码可以帮助网页在搜索结果中获得更好的展示效果。<p>4. 响应式设计：一种通过使用HTML和CSS来使网页适应不同屏幕大小和设备的设计方法。通过响应式设计，可以提供更好的用户体验和跨平台兼容性。<p>5. HTML5：HTML的最新版本，引入了许多新的标签和功能，如音视频、Canvas绘图、地理位置等。学习HTML5可以使你能够使用更丰富的特性来构建现代化的网站和应用。<p><p>总之，HTML标签是构建网页结构和内容的基础，熟悉并正确使用这些标签是每个开发者必备的技能。同时，与HTML相关的其他知识点也是进一步提升网页开发技能的关键。 <p><b><a href="https://www.yihanseo.com/" title="宁波壹涵网络科技有限公司">壹涵网络</a></b>我们是一家专注于网站建设、企业营销、网站关键词排名、AI内容生成、新媒体营销和短视频营销等业务的公司。我们拥有一支优秀的团队，专门致力于为客户提供优质的服务。</p>
