Houdini is a set of low-level APIs that exposes parts of the CSS engine. Hence, giving developers the power to extend CSS by hooking into the styling and layout process of a browser’s rendering engine. Houdini is a group of APIs that give developers direct access to the CSS Object Model (CSSOM), enabling developers to write code the browser can parse as CSS, thereby creating new CSS features without waiting for them to be implemented natively in browsers. Also, it takes quite long for new CSS features to come to the browsers. Houdini will help bring them faster.
This would look great but there are a few things to keep in mind before using it. Those are:
- With Houdini you could invent your own masonry, grid, or regions implementation, but doing so is not necessarily the best idea. The CSS Working group does a lot of work to ensure every feature is performant, handles all edge cases, and considers security, privacy, and accessibility. But as you extend CSS with Houdini, make sure to keep these considerations in mind.
