I recently received an HTML file that was created using Tailwind CSS and now I am looking for a way to convert everything to regular CSS. I found a tool that converts individual classes, but it would require me to extract and paste thousands of classes one by one. Is there a simpler solution where I can upload the entire HTML file and generate a CSS version automatically? I would prefer an online tool rather than installing multiple third-party applications, learning their systems, completing the conversion, and then uninstalling everything afterwards.
