CSS3

CSS3, or Cascading Style Sheets Level 3, is a style sheet language used to describe the visual presentation of web pages. Think of it as the design toolkit for websites, allowing developers to control layout, colors, fonts, and spacing. CSS3 introduced new features such as rounded corners, shadows, gradients, and animations, enhancing the aesthetic appeal without compromising performance. This separates content from design, making it easier to maintain and update. Overall, CSS3 plays a vital role in ensuring that websites are not only functional but also visually engaging for users.
