CSS frameworks and usage

CSS frameworks, such as Tailwind and Bootstrap, are widely adopted and used by developers for building user interfaces (UI). While Tailwind has high interest and usage, Bootstrap remains the most widely used CSS framework. However, interest in Tailwind is decreasing, suggesting a possible saturation point. Other lesser-known frameworks like Foundation have seen a decline in interest and awareness. The popularity of CSS-in-JS frameworks has also decreased, with many developers preferring regular CSS and leveraging CSS variables for dynamic styling. Second-tier CSS frameworks, such as UIKit and Bulma, offer alternatives with varying levels of adoption and popularity.
