href="#前端开发到底是什么"><span>前端开发到底是什么？</span></a></h2><p>前端开发，简单来说，就是<strong>你能在网页上看到和互动的一切</strong>。</p><p>想象一下你正在看一个网站：</p><ul><li><strong>文字、图片、按钮、菜单</strong>：这些都是前端开发人员用代码“画”出来的。</li><li><strong>点击按钮会发生什么、输入框能打字、图片能放大缩小</strong>：这些互动效果也是前端开发人员用代码实现的。</li></ul><p>所以，前端开发就是负责把设计师画好的网站样子，用代码变成用户可以在浏览器里真实看到、摸到、用的东西。它主要涉及三种技术：</p><ol><li><strong>HTML</strong>：就像网页的“骨架”，决定了网页上有什么内容（标题、段落、图片等）。</li><li><strong>CSS</strong>：就像网页的“衣服”，决定了网页看起来怎么样（颜色、字体、布局等）。</li><li><strong>JavaScript</strong>：就像网页的“大脑”，决定了网页能做什么（动画、交互、数据处理等）。</li></ol><p>总而言之，前端开发就是让网站变得好看、好用、能互动。</p><h2 id="开发工具" tabindex="-1"><a class="header-anchor" href="#开发工具"><span>开发工具</span></a></h2><p>进行前端开发，我们需要一个好用的“工具箱”。其中，<strong>Visual Studio Code (VS Code)</strong> 是一个非常受欢迎且功能强大的选择。</p><p>VsCode 官网：<a href="https://code.visualstudio.com/" target="_blank" rel="noopener noreferrer">https://code.visualstudio.com/</a></p><p><strong>为什么推荐 VS Code？</strong></p><ul><li><strong>免费且开源</strong>：你可以免费使用它，并且它的代码是公开的，有很多人一起维护和改进。</li><li><strong>轻量级但功能强大</strong>：它启动速度快，占用资源少，但通过安装各种“插件”，可以实现非常多的功能，比如代码高亮、智能提示、调试、版本控制等等。</li><li><strong>支持多种语言</strong>：不仅对 HTML、CSS、JavaScript 有很好的支持，也支持其他很多编程语言。</li><li><strong>丰富的生态系统</strong>：有大量的插件可以帮助你提高开发效率，比如 Live Server（实时预览网页）、Prettier（代码格式化）等。</li><li><strong>跨平台</strong>：无论你使用 Windows、macOS 还是 Linux，都可以安装和使用 VS Code。</li></ul><h3 id="vscode-前端开发插件推荐" tabindex="-1"><a class="header-anchor" href="#vscode-前端开发插件推荐"><span>VsCode 前端开发插件推荐</span></a></h3><ul><li><strong>Chinese (Simplified) Language Pack for
