npm add yieldcssYield CSS lets you generate CSS on-the-fly, making it perfect for a serverless environment like Cloudflare Workers.
Instead of using tooling to compile written files to other files and then uploading those somewhere, you write functions that output the CSS you want on-the-fly.
This mean you can have conditional CSS, substitute variables, run calculations, and write loops to automate repetitive CSS. You have the full power of JavaScript at hand.
