Cascading Style sheet

Introduction to CSS (Cascading Style Sheets)

CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML or XML. While HTML provides the structure and content of a webpage, CSS defines how these elements are displayed visually, enabling the design of beautiful, responsive, and user-friendly websites.

CSS allows developers to control the layout, colors, fonts, and overall look of the website, making it a crucial tool in web development.

Key Features of CSS:

1. Cascading: The term "cascading" refers to the way CSS applies rules. If there are conflicting styles for an element, the rule closest to the element (in terms of specificity) is applied. This ensures that more specific rules take precedence over more general ones.
2. Separation of Concerns: CSS helps separate content from presentation. HTML handles the content structure, while CSS handles how the content looks, making the website easier to maintain and more flexible to design changes.
3. Responsive Design: CSS supports media queries and responsive units, making it easier to build websites that adapt to different devices and screen sizes.
