What is the term for the part of a CSS rule-set that defines which HTML elements the style should be applied to?

• A. CSS Class
• B. CSS Selector
• C. Property
• D. Sprite

Answer: (B)

Selectors identify the HTML elements that should receive the styling. In a CSS rule-set, the selector appears before the curly braces and tells the browser which elements to target. For example, p { color: red; } targets all paragraph elements. You can combine or refine targets with different selector types, such as .note for elements with a specific class or #header for a specific id, and even more complex patterns like a selector that targets a specific element inside another. Inside the braces are properties like color or font-size that define the actual styles applied to those targeted elements. The other terms are related but refer to different parts: a class is a type of selector, a property is a style attribute within the rule-set, and a sprite is an image used for graphics. The part that names the elements to style is the selector.
