CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML or XML, including various XML languages like SVG and XHTML. CSS defines how elements should be rendered on screens, paper, in speech, or on other media, playing a vital role in web development and design.

1. Developer CSS was developed by the World Wide Web Consortium (W3C), with significant contributions from Håkon Wium Lie and Bert Bos. Håkon Wium Lie first proposed the concept of CSS in 1994 to address the challenges of document presentation on the web, which was previously controlled solely by HTML.

2. Purpose The primary goal of CSS was to separate the content of a document (HTML) from its presentation aspects (fonts, colors, layout). This separation made web development more accessible and allowed web pages to adapt more easily to different devices.
