I found that the official website of reflex is the best reflex "template" to date. It has a good design, is responsive, and has a Landing page. However, the original repository is very complex, with many files, and compiles very slowly. Therefore, this streamlined project was created. I copied the code from the official repository, then reduced, reduced, and reduced it again with some adjustments. I hope this can serve as a simple starting template.
If you find *.py in templates/ folder not been highlighted, you can use command ctrl+shift+p and type Change Language Mode to change the language mode to Python.
