CSS3

What is it?

CSS3 (Cascading Style Sheets Level 3) is the latest evolution of CSS used to define the presentation and layout of web content. It extends earlier versions with modular features and advanced visual capabilities.

What does it do?

CSS3 controls the look and feel of web pages, including layout, colors, typography, spacing, animations, and responsiveness. It allows developers to build adaptive interfaces without relying heavily on JavaScript.

Where is it used?

CSS3 is used in all modern websites and web applications, including SaaS platforms, dashboards, mobile web apps, landing pages, PWAs, and design systems.

When & why it emerged

CSS3 development began in the late 2000s as web interfaces became more complex. It emerged to support responsive design, richer visuals, and better separation of content and presentation.
