Houdini is a collection of APIs that expose the CSS engine's internals to developers. CSS does an amazing amount of work when it comes to UI / UX. You change a single attribute and suddenly your entire website appears in a different layout. Houdini CSS is a new collection of browser APIs which allow you to gain more access to your browser’s CSS engine. The APIs are accessible through JavaScript, making them web developer friendly.

Houdini also attempts to resolve some of the more difficult things around CSS development, which is, at times, extremely delicate by nature.
