HEADLESS, BONELESS, SKINLESS, & LIFELESS UI

Summary from the TLDR Web Dev newsletter

There are four categories of UI abstractions: Headless UI, Boneless UI, Skinless UI, and Lifeless UI. Headless UI is a common term where the abstractions often have underlying functionality and structure. Boneless refers to UI libraries that provide composable styles but no markup. Skinless UIs provide functioning markup with no styling. Lifeless UI abstractions, like TanStack, offer typesafe hooks and logic without rendering actual UI elements, leaving the developer responsible for applying those functions to elements and styles.
