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.
