What is OOCSS?

OOCSS (Object-Oriented CSS) is a CSS architecture methodology that encourages developers to write reusable, modular, and maintainable CSS code. It is based on two main principles: separating structure from skin (separating layout/position from visual properties like colors and typography) and separating containers from content (avoiding CSS rules that depend on the container's context). This approach leads to smaller CSS files, faster loading times, and improved maintainability.
