Object Oriented CSS (OOCSS) is a CSS framework and methodology by Nicole Sullivan that promotes separating structure from skin and container from content to create reusable, scalable stylesheets. It was highly influential in shaping modern CSS architecture but is no longer actively developed.

Use cases

• learn object-oriented CSS principles and methodology
• structure large CSS codebases with reusable modules
• study the origins of modern CSS architecture like SMACSS and BEM
• find a lightweight CSS framework for legacy web projects
• understand how to separate CSS structure from visual skin

When to choose

• you want to study the foundational OOCSS methodology that influenced modern CSS practices
• you maintain a legacy project already built on OOCSS conventions
• you need a minimal, dependency-free CSS approach rather than a full component framework

When to avoid

• you need an actively maintained framework with current browser support and security updates
• you are starting a modern project where utility-first frameworks like Tailwind or CSS-in-JS solutions are a better fit
• you expect documentation, releases, or community support - the project has been dormant for years
