What does the acronym CSS stand for?

The acronym CSS stands for Cascading Style Sheets. This terminology is essential in web development as CSS is a stylesheet language used for describing the presentation of a document written in HTML or XML. It allows developers to control the layout and appearance of web pages, including aspects such as colors, fonts, spacing, and positioning of elements.

Cascading refers to the way styles can cascade down from parent elements to child elements, allowing for a hierarchical structure in styling that provides flexibility and consistency throughout a website. The significance of CSS extends to improving the user experience and accessibility of web content, making it a fundamental component of modern web development. Understanding CSS is crucial for anyone involved in creating or maintaining websites, as it separates the visual presentation from the content, enabling easier updates and maintenance.
