Syntax - Tasty Web Development Treats

The messy breakup is official; as of November 12, OpenAI's models are getting pulled from Cursor, and we're digging into who's really to blame (and why Wes called it). Plus pnpm 12 goes full Rust, Mitchell Hashimoto drops Superlogical, ~700 AI agents attack Hugging Face, and Zod 4.5's compiled schemas get up to 9x faster.

Meta’s StyleX compiles thousands of styles into a few reusable class names at build time—zero runtime, fully type-safe. Scott and Wes break down why it’s suddenly everywhere, and why it might be the best CSS tool for AI agents.

Scott and Wes run through eight new CSS, JS, and HTML features landing in browsers; including the relative alpha() color function, the progress() function for calculating values between units, Promise.allKeyed(), and native camera and microphone elements. They also get into an upgraded attr(), shrink-to-fit containers, and text-box-trim for finally killing that annoying extra space above your text.
