Help me collect fun free online course website.

Hi, I need someone to help me collect some fun, free online course websites, which is all about frontend development, so I could translate it into Chinese for sharing with people~. the website could be yours, or some projects on the GitHub. for example, if you have such a website, like this [login to view URL], and then you are willing to let me translate it into Chinese and give me the code, we could make this deal, or if it brings more money to me in the future, you may also get some bonus. what you need to do is find the source code and I'll translate it into Chinese. Just pay attention to the copyright. If you have such resources, you could show me the links, or screenshot, with descriptions, and the price you want. it will be also great if you are willing to do something and help me deploy it easier~
