HTML概述与基础架构
在现代互联网的世界中，HTML（超文本标记语言）是构建网页的核心技术之一。它是一种用于创建网页的标准标记语言，通过一系列标签来定义网页的内容和结构。本文将简要介绍HTML的基本概念及其核心组成部分。
首先，HTML的主要功能在于描述网页中的各种元素，如文本、图片、链接等。通过使用不同的标签，开发者可以轻松地组织页面内容并赋予其特定的意义。例如，“`以及可能需要加载的外部资源如CSS或JavaScript文件。
4. 主体实际显示给用户看的部分写在`<body>`标签内部。这里可以放置所有的可见内容，包括文字、图像、视频以及其他嵌套结构。
5. 语义化标签：为了提高代码可读性和搜索引擎优化效果，推荐使用具有明确含义的语义化标签，如`<header>`、`<footer>`、`<nav>`等代替通用的`<div>`。
总之，掌握HTML的基础知识对于任何想要涉足Web开发领域的人来说都是至关重要的第一步。随着实践积累和技术进步，你可以进一步探索CSS样式设计和JavaScript交互编程，从而打造更加丰富多样的在线体验。希望这篇简短的介绍能为你打开学习HTML的大门！ </div>
