Sure! Let's go through each of these CSS concepts in detail.

1. Introduction to CSS

CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation and design of a document written in HTML. It controls the layout, colors, fonts, spacing, and overall visual appearance of web pages.

Why is CSS Important?

Without CSS, web pages would look plain and unstyled. CSS helps in:

• Separating content from presentation, making the code cleaner.
• Enabling responsive designs that adapt to different screen sizes.
• Reducing repetition by defining styles once and applying them to multiple elements.
• Enhancing user experience with animations, transitions, and effects.
