What is CSS & What Is It Used For?

CSS, short for Cascading Style Sheets, is a crucial component of web design, focusing on the presentation and layout of web pages. While HTML provides the structure, CSS dictates how that structure is styled and displayed. Let’s delve into the world of CSS:

Basics of CSS

  1. Styling Language: CSS is a styling language used to describe the look and formatting of a document written in a markup language like HTML. It defines how elements should be displayed on screen, paper, or in other media.
  2. Separation of Concerns: CSS separates the content of a webpage (HTML) from its presentation, allowing for greater flexibility and easier maintenance.
