CSS
CSS (Cascading Style Sheets) is like the interior designer for websites - it controls how websites look and feel. While HTML provides the basic structure of a webpage, CSS handles everything about its appearance: colors, layouts, spacing, and how it looks on different devices like phones or computers. Think of it as the difference between having the walls and rooms of a house (HTML) and then decorating those rooms with paint, furniture, and arrangements (CSS). It's an essential skill for anyone working on websites, particularly front-end developers who focus on what users see and interact with.
