CSS, which stands for Cascading Style Sheets, is the language used to style and design the visual presentation of a website. While HTML provides the structure (like the bones and muscles), CSS provides the "skin," clothes, and overall aesthetic. Developed by the World Wide Web Consortium (W3C), it allows you to apply colors, fonts, layouts, and animations to your web pages, separating the content from the design.

C is a general-purpose, procedural computer programming language developed in the early 1970s by Dennis Ritchie at Bell Labs. It was originally designed to build the Unix operating system, but it has since become one of the most widely used and influential languages in history. Often referred to as a "middle-level" language, C combines the capabilities of low-level assembly (direct hardware manipulation) with the readability of high-level languages.
