CSS (Cascading Style Sheets) was proposed and developed by Håkon Wium Lie and Bert Bos. They were both part of the team at CERN (European Organization for Nuclear Research) that was working on developing a standard for styling web documents. Lie, a web pioneer, and Bos, a computer scientist, collaborated to create CSS as a way to separate the presentation of a webpage from its structure. Their efforts revolutionized web design by providing a more efficient and flexible method for styling web content.

The declaration block is the section of CSS where the property or value pairs appear. It is enclosed within curly braces ({}) and contains one or more declarations. Each declaration consists of a property, followed by a colon (:), and then the corresponding value.
