在不同IDE中实现CSS/JS动画：WOW.js与其他库的集成

本文旨在解决将Codepen上的CSS/JS动画（特别是基于WOW.js的动画）迁移到其他IDE时遇到的依赖问题。通过详细列出所需的外部CSS和JavaScript库（如Animate.css、jQuery、WOW.js、Font Awesome和Google Fonts）的CDN链接，并提供完整的代码结构，确保动画在任何开发环境中都能正确运行，并解释了各库的作用及集成要点。

在web开发中，我们经常利用css和javascript库来增强用户界面的视觉效果和交互性。像wow.js这样的库能够实现滚动时触发的动画效果，结合animate.css等动画库，可以轻松创建动态的网页内容。然而，当我们将这些在在线开发环境（如codepen）中正常运行的代码迁移到本地ide或其他项目中时，常常会遇到“xxx is not defined”之类的错误，这通常是由于缺少必要的外部资源引用所致。本教程将详细阐述如何正确引入这些外部依赖，以确保您的动画在任何环境中都能顺利运行。

核心问题：缺失的外部依赖

在Codepen这类在线平台上，许多常用的库可能已经默认引入，或者通过简单的配置即可使用。但在本地开发环境中，您需要手动引入所有外部CSS样式表和JavaScript脚本。当您看到类似WOW is not defined的错误时，这意味着浏览器无法找到WOW这个全局对象，因为它所依赖的WOW.js库文件尚未被加载。

为了使动画和相关功能正常工作，我们需要引入以下关键库：

Google Fonts: 用于加载自定义字体，提升页面美观度。
Font Awesome: 提供丰富的图标字体，常用于美化UI元素。
Animate.css: 一个预设的CSS动画库，WOW.js通常与之配合使用以实现各种动画效果。
jQuery: 一个流行的JavaScript库，简化了DOM操作、事件处理、动画和Ajax交互。本例中的JavaScript代码使用了jQuery的选择器和方法。
WOW.js: 一个轻量级的JavaScript库，用于在用户滚动页面时显示CSS动画。它会检测带有特定CSS类（如wow和fadeInRight）的元素，并在它们进入视口时添加动画效果。

引入必要的库文件

所有外部资源通常通过CDN（内容分发网络）链接引入，这能够加快加载速度并减轻服务器负担。您需要在HTML文件的

标签内引入CSS文件，并在标签的底部（之前）引入JavaScript文件，以确保DOM元素在脚本执行前已加载。

以下是实现给定动画所需的所有CDN链接：
