What does CSS stand for?

CSS stands for Cascading Style Sheets. This term refers to a style sheet language used for describing the presentation of a document written in HTML or XML. It allows web developers to separate content from design, enabling them to specify how elements should be displayed on the screen, paper, or in other media.

The "cascading" aspect of CSS means that styles can cascade down from multiple sources, allowing for flexibility and ease of management. Styles can be defined in several ways: inline, internal, or external stylesheets. External stylesheets, which are separate files that can be linked to multiple HTML documents, enable consistency across a website while allowing for easy updates.

This structured system not only promotes better organization and cleaner code but also improves web design applications by allowing for responsiveness and adaptability in shape and format depending on the viewing device. By understanding that CSS stands for Cascading Style Sheets, one can appreciate the significance of styling web pages, which enhances user experience and functionality.
