What is Declaration?

A declaration in CSS is a single statement that specifies a property you want to style and the value you want to assign to that property. It's the fundamental building block for applying styles to HTML elements. Each declaration consists of a property name (like color or font-size), followed by a colon (:), and then a value (like red or 16px). Declarations are always placed inside a CSS rule set, within the curly braces {}.
