HTML（HyperText Markup Language）是一种用于创建网页的标准标记语言，其核心功能是通过标签定义网页的结构和内容。以下是关于HTML的详细解析：

一、基本定义

非编程语言
HTML 不是一种编程语言，而是标记语言。它通过预定义的标签（如 `
`, ``, `` 等）指示浏览器如何呈现网页内容。
超文本特性
支持嵌入图片、视频、音频、链接等多媒体元素，实现文本与超媒体的结合。
二、核心功能
结构化内容
通过标签定义网页结构，如段落、标题、列表、表格等。
语义化标记
标签具有明确的语义，便于浏览器解析和搜索引擎优化（SEO）。
与CSS和JavaScript协同
- CSS负责样式设计，JavaScript实现交互功能。
三、基础结构
一个典型的HTML文档包含以下部分：
文档类型声明：

HTML标签：成对出现（如 `` 和 ``）

常用标签：

文本内容：`

`, `

`-`

`
链接：``
图片：``
表单：``, `` 等</p><p> 四、特点与优势</p><h3>跨平台性：</h3><p>浏览器直接解析HTML文件，无需编译。</p><h3>可扩展性：</h3><p>可通过CSS和JavaScript增强功能。</p><h3>通用性：</h3><p>适用于各类网页开发，是Web开发的基础。</p><p> 五、应用场景</p><p><strong>网页开发</strong>：构建静态及动态网页内容。</p><p><strong>UI自动化</strong>：辅助定位网页元素进行测试。</p><p><strong>数据展示</strong>：与后端技术结合实现动态数据更新。</p><p> 总结</p><p>HTML是Web开发的基石，通过标记语言实现网页结构化呈现。掌握HTML是学习CSS、JavaScript等技术的必要前提，也是构建交互式网站的基础。</p>   <div class="wenanna372b-8bcf-1437-4a43 art-copyright br mb"> <div> <strong class="wenanna8bcf-1437-4a43-6e45
