Honest question. Not trying to offend any css fans here.
Why would someone use this nowadays instead of just using AI? To me the purpose of these small css frameworks was to have a nice consistent UI quickly. What is the value of these frameworks now?
Two answers I can think of:
1. Believe it or not: some people are still not using AI.
2. AI generated websites tend to look very similar. Having a clean starting point and then tweaking the style to your liking avoids the obvious AI-stink.
Sometimes I don't want to take out the stand mixer and just mix things by hand. I prefer to walk to the grocery store rather than take the car. I don't always use a drill where a screwdriver will do.
Same reasoning.
