Making my own framework. Any tips?

Hello, I am currently making my own HTML+CSS+JS framework, you can view it at my GitHub Repository here: github.com/29cmosier-dev/ZiggyLabs-Framework

I call it ZiggyLabs Framework for now, I might rename it, and my main goal is to reduce the HTML clutter that Bootstrap has, and possibly figure out more goals later.

I would also like to show off my navbar, as you can see from this post's image above.

I am currently working on setting up Version 1, as of right now I am working on finishing card styles, next I will either work on modals or buttons, possible both. If anyone is interested, feel free to let me know and suggest ideas on what features to code next!
