What Is CSS?

CSS stands for Cascading Style Sheets. It is used to control the visual appearance of websites. While HTML defines structure, CSS defines how content looks.

CSS controls colors, fonts, spacing, layouts, and responsiveness. It allows websites to adapt to different screen sizes and devices.

Styles can be applied globally or to specific elements. This separation of content and design improves maintainability.

Modern CSS includes advanced features such as Flexbox and Grid, which simplify complex layouts.

Poorly written CSS can slow down websites, while clean CSS improves performance and readability.

In summary, CSS transforms plain HTML into visually appealing websites. It is an essential skill for front-end development.
