The theory behind OOCSS according to Nicole Sullivan

In this article, I introduce to you the concept of object oriented CSS. I came to learn about Object Oriented CSS from Smashing Magazine. Until I read the online article on it’s website, I didn’t know that CSS could be such a powerful tool and what we can do with it. Nicole Sullivan, is a CSS guru who started the OOCSS.org. She has been hired by Facebook to optimize their CSS files.
Nicole first presented the Object Oriented CSS at Web Directions North, in Denver. The response has been overwhelming. According to Nicole, OOCSS allows you to write fast, maintanable and re-usable codes. It makes for a more efficient stylesheet that is easier to add and to maintain.
