What does CSS stand for, and what does the full expansion of the abbreviation mean?
The abbreviation CSS stands for Cascading Style Sheets.
Cascading refers to how the rules of the style sheet are applied based on order precedence. If there is more than one of the same rule that applies to the same element, the rule that comes later will have greater precedence. In addition, if we link multiple style sheets, the rules from the style sheets that are linked later will have greater precedence than the earlier linked ones.
A Style Sheet is a type of file or language that describes the presentation of a structured document. It is a way to apply “separation of concerns”, by separating the structure (HTML) from the style (CSS). CSS is a particular type of style sheet, mainly used for the Web, to describe the presentation of markup languages such as HTML.
