CSS vs CSS3: Understand the Difference Between CSS and CSS3

Web design is a vital aspect of creating engaging and user-friendly websites. It determines how a website appears and functions on the internet, significantly influencing the overall user experience. One of the key technologies behind web styling is CSS (Cascading Style Sheets), which works alongside HTML to shape a webpage’s layout, design, and visual appeal. The evolution of CSS to CSS3 has brought numerous advancements, including animations, transitions, and responsive designs, making websites more dynamic and interactive.

In this article, you’ll explore the difference between CSS and CSS3, gaining insights into their unique features and understanding why CSS3 is a game-changer in modern web development. Whether you’re a beginner or preparing for HTML CSS interview questions, mastering these differences is essential.

What is CSS? 

CSS (Cascading Style Sheets) is a styling language used to describe the visual presentation of HTML documents. It defines how elements on a webpage—such as text, images, and layouts—are displayed. CSS works in harmony with HTML to separate content from design, allowing developers to create visually appealing and organized websites. 

With the advent of CSS3, web styling has advanced significantly, enabling more dynamic and interactive designs. Understanding the difference between CSS and CSS3 is essential for modern web development.
