Introduction to CSS

CSS stands for Cascading Style Sheets. It is a stylesheet language used to describe the presentation of a document written in HTML. While HTML builds the skeleton structure, CSS is the coat of paint — it controls layouts, colors, fonts, and animations.

HTML alone is boring. CSS brings it to life:

To understand the difference, think of building a house. HTML is the skeleton — walls, beams, structure. CSS is the design — paint, roof color, decor.

CSS gives you power over almost every visual aspect of the page: - Colors: Text color, background color, borders. - Typography: Fonts, size, bold/italic, line height. - Layout: Margins, padding, grid, alignment. - Effects: Animations, hover states, shadows.
