我有一个由2个HTML文件、6个CSS文件和11个JS文件组成的小型本地Web应用程序。
如果这些文件都复制粘贴到单个HTML文件中（适当地），例如将JS放在头部的<script>标签中，将CSS放在<style>标签中，那么Web应用程序还能正常工作吗？
是否有工具可以自动且安全地将JS、CSS和HTML文件集合合并为单个HTML文件？
在网上搜索时，我只发现可以合并或压缩一种类型文件的工具，但没有创建合并HTML文件的工具（例如AIOM+、HTMLcompressor）。我找到了这个名为Inliner的应用程序，但似乎是在我不熟悉并且当前不使用的Node.js上运行的。
简而言之，我要么寻找一个简单的独立工具，可以读取HTML中所有链接的文件，并通过附加这些文件的内容来重写HTML。如果这太困难了，那么只需确认手动完成工作将产生一个可用的文件，或者在这样做时需要注意的任何提示。谢谢！
我为此编写了一份简单的Python脚本。
这是我的树:
root-folder
├── index.html
├── build_dist.py
├── js
│ └── somescript.js
├── css
│ ├── styles1.css
│ └── styles2.css
└── dist
我运行了这个脚本：
cd root-folder
python build_dist.py
一般来说，是的。
我不知道如何合并多个HTML文件，但是这里有一个Python脚本（Github），可以将CSS / JS /图像合并到一个单独的HTML文件中。与Noam Nol的回答相比...
用法： python3 htmlmerger yourfile.html
htmlmerger.py以下是Github文件的内容。
