The initial proposal for CSS was made by Håkon Wium Lie in 1994. While he spearheaded the idea, CSS wasn't the work of a single individual but rather a collaborative effort over time. Here's a breakdown of CSS's development:

Key Contributors
While Håkon Wium Lie is often credited as the originator of CSS, it's essential to note that many individuals contributed to its evolution. The collaborative nature of web standards development means that improvements and new features were often a group effort within organizations like the World Wide Web Consortium (W3C).
Understanding CSS
CSS, or Cascading Style Sheets, is a styling language used for describing the look and formatting of a document written in a markup language such as HTML. Here’s how it works:
- Separation of Concerns: CSS separates content (HTML) from its visual presentation.
- Cascading: Styles are applied based on a hierarchy, allowing for a structured approach.
- Style Definitions: CSS defines styles through rules, each containing selectors and declarations that specify how HTML elements should appear.
Conclusion
In conclusion, Håkon Wium Lie proposed the idea of CSS, but its development was a collaborative process involving many individuals and organizations, with the initial version being released in 1996.
