Tailwind CSS has completely changed how I think about styling my components. As a backend-leaning full stack dev, I used to HATE CSS with a burning passion and never took the time to really learn it. Over time I picked up some tricks here and there but never felt comfortable when it came time to make things look nice.
Ever since I started using Tailwind CSS I feel like this has completely changed. It is so easy to discover where the styles are being applied, and it is just as easy to discover how to do something that you didn't know prior. The discoverability here is huge and I feel like I am a much better front end dev because of this tool.
