In the context of style sheets, what is the term for a format instruction that includes a specified selector with properties and values?

• A. style rule
• B. style declaration
• C. CSS rule
• D. style property

Answer: (A)

The correct term for a format instruction that includes a specified selector along with properties and values is known as a style rule. A style rule is a complete set that begins with a selector, which targets the HTML element(s) you want to style, and is followed by declarations enclosed in curly braces. The declarations consist of individual properties and their corresponding values, which determine how the selected elements will be presented on the web page.

For instance, in the style rule p { color: blue; font-size: 16px; }, p is the selector that targets paragraph elements, and the declarations color: blue; and font-size: 16px; specify how those paragraph elements should be styled.

In this context, other options do not fully encapsulate the complete definition of a style rule. A style declaration refers specifically to the properties and values used within a style rule, while CSS rule is an informal term that could be interpreted similarly to style rule but is less precise in the context of formal terminology. A style property is simply one part of a style declaration, representing a specific aspect of styling (like color or font size) without the context of being associated with a selector. Thus, “style rule” accurately
