What is the meaning of cascading?

Answer 1

The cascading that is referred to in the name cascading style sheets refers to how rules can cascade in how they are implement. CSS rules can be found in three places: an external style sheet, and internal style sheet, or inline. Cascading refers to precedence. A rule located inline, will take precedence over a rule located in an internal style sheet and a rule located in an internal style sheet will take precedence over a rule located in an external style sheet. Within a single style sheet (for example an external style sheet) a rule located at the bottom of the style sheet takes precedence over a rule located at the top of the style sheet. This allows you fine tuned control over your styles and how and when they display and which one will display based upon where in the cascading hierarchy they appear.
