According to NPM download stats, it has 6 million weekly downloads, the exact same amount as Styled Components. Emotion also has around 6 million. So that's 12 million for CSS-in-JS, as opposed to 6 million for Tailwind, so how did it win?
And this is ignoring PostCSS which has over 60M downloads weekly. But I guess you can use postcss with tailwind.
Like... It has won nothing, its in the game though.
