CSS: the cascade, specificity, and inheritance

Specificity is a method of conflict resolution within the cascade. Specificity is calculated in a very particular way, based on the values of 4 distinct categories. For explanatory purposes, the CSS2 spec represents these categories using the letters a, b, c, and d. Each has a value of 0 by default. a is equal to 1 if the declaration comes from a style attribute in the HTML (“inline styles”) rather than a CSS rule with a selector.b is equal to the number of ID attributes in a selector.c is equal to the number of other attributes and pseudo-classes in a selector.d is equal to the number of elements and pseudo-elements in a selector.

The specificity is given by concatenating all 4 resulting numbers. For example, the selector #id .class[href] element:hover contains: 1 ID (b is 1)1 class, 1 attribute selector, and 1 pseudo-class (c is 3)1 element (d is 1) Therefore, it has a specificity of 0,1,3,1.

Patterns For Large-Scale JavaScript Application Architecture

The material is based on my talk of the same name, last presented at LondonJS and inspired by previous work by Nicholas Zakas. Who am I and why am I writing about this topic? I'm currently a JavaScript and UI developer at AOL helping to plan and write the front-end architecture to our next generation of client-facing applications. As these applications are both complex and often require an architecture that is scalable and highly-reusable, it's one of my responsibilities to ensure the patterns used to implement such applications are as sustainable as possible.

I also consider myself something of a design pattern enthusiast (although there are far more knowledgeable experts on this topic than I). Can you summarize this article in 140 characters?
