CSS vs CSS3

CSS (Cascading Style Sheets) and CSS3 are closely related, but they refer to different versions of the same style sheet language used for web design. Let’s compare CSS and CSS3:

CSS (Cascading Style Sheets):

1. Definition: CSS is a style sheet language used to control the presentation and layout of HTML and XML documents. It was first introduced in 1996 as CSS1 and then updated to CSS2 in 1998.
2. Selectors and Properties: CSS allows you to select HTML elements and apply various styling properties to them. CSS2 introduced new selectors and properties compared to its predecessor, CSS1.
3. Features: CSS allows you to set properties such as color, font, margin, padding, background, positioning, etc. It’s widely used for basic styling and layout of web pages.
4. Browser Support: Almost all modern web browsers support CSS.

CSS3:

1. Definition: CSS3 is the latest version of CSS and includes several new features and improvements over CSS2. It is not a completely separate language but an extended version of CSS2.
2. Modules: CSS3 is divided into several modules, each focusing on specific features and improvements. Examples of modules include Selectors Level 3, Box Model, Backgrounds and Borders, Transitions, Animations, Flexbox, Grid Layout, etc.
3. New Features: CSS3 introduces a wide range of new properties and features, providing more control and flexibility for web designers. Some notable features include border-radius for rounded corners, box-shadow for adding shadows, and @media queries for responsive design.
4. Browser Support: Most modern web browsers support CSS3, but some older browsers might have limited or no support for some CSS3 features. In such cases, developers often use fallbacks or vendor prefixes to ensure a consistent experience across different browsers.

Overall, CSS3 is an evolution of CSS that brings significant improvements, new features, and better control over web page design. It’s important to note that “CSS” often colloquially refers to both CSS2 and CSS3, as CSS3 builds upon the foundation of CSS2 and is considered the current standard for web styling. Web developers commonly use various CSS3 features to create modern and responsive web designs.
