Summary
The word ???cascading??? in the name Cascading Style Sheets refers to the way that
styles cascade from various style sheet sources to the elements in the document
tree. The CSS cascade (p. 118) is the process of resolution that determines the final
value of a property when multiple applicable declarations exist for that property.
The process can be summarized as:
1. Find all declarations that apply to a specific element.
2. Sort the declarations according to their importance and origins.
3. Sort declarations with the same levels of importance and origin by selector
specificity.
4. Sort declarations with the same levels of importance, origin, and specificity by
their source order.
To calculate the priority of importance and origin, the cascade uses this list (in
order from lowest to highest priority):
1. user agent declarations
2. normal declarations in user style sheets
3. normal declarations in author style sheets
4. important declarations in author style sheets
5.
