CSS is a language used to control the layout, colors, fonts, and other visual elements of a web page, and is essential for creating attractive and responsive web designs. It was first proposed in 1994 by a group of developers at the World Wide Web Consortium (W3C). In 1996, CSS was released as a simple language that allowed developers to specify basic styles for web pages, such as font size, color, and background. In 1998, CSS2 was released, which introduced new features such as absolute positioning, floating elements, and support for printing. In the early 2000s, CSS began to gain wider adoption and acceptance among web designers and developers.


CSS was seen as a way to create more attractive and responsive web designs, and it provided a more comprehensive way to control the visual presentation of web pages. In 2002, the W3C released a new version of CSS called CSS2.1, which included minor updates and improvements to the language, and helped to establish CSS as a reliable and stable standard for web design. In 2005, the first version of CSS3 was released, which introduced new features such as rounded corners, gradients, and animations. In 2018, the W3C released the latest version of CSS, called CSS4. CSS4 is not a complete overhaul of the language, but rather a collection of new modules and features that have been developed and tested over the years.


Today, CSS is an essential tool for creating web designs that are attractive, responsive, and functional. It has come a long way since its early days in the mid-1990s, and its continued evolution and improvement is a testament to the power of innovation and collaboration in the technology industry.
