**网页设计 源代码**

在网页设计的世界里，源代码是构建美丽界面的基石。HTML、CSS和JavaScript是构成网页的三大核心语言。它们共同协作，为用户呈现丰富多彩的网页内容。

HTML，全称为超文本标记语言，是网页的骨架。它定义了网页的基本结构和内容。每一个HTML文档都从开始，定义了文档类型和HTML版本。随后是标签，它包裹了整个网页的内容。在部分，我们放置了网页的元数据，如定义了网页的标题，而<link>和<script>则分别用于链接外部CSS和JavaScript文件。<br/><br/><body>标签内则包含了网页的主体内容，如<header>、<nav>、<main>、<footer>等。这些标签不仅为内容提供了语义化的标记，还有助于搜索引擎和辅助技术更好地理解网页内容。<br/><br/>CSS，层叠样式表，为网页增添了色彩和样式。通过选择器，我们可以为HTML元素定义字体、颜色、背景、边距等样式属性。CSS不仅可以使网页更加美观，还能提高网页的加载速度和用户体验。<br/><br/>JavaScript，一种脚本语言，为网页带来了交互性。它可以响应用户的点击、滑动等操作，实现动态效果、表单验证、数据交互等功能。通过JavaScript，我们可以为网页增添更多的功能和趣味性。<br/><br/>综上所述，HTML、CSS和JavaScript是网页设计的三大支柱。它们共同构成了网页的源代码，为用户带来丰富多彩的网页体验。
