Which of the following statements about CSS selectors is correct?

• A. Id selectors are prefixed with a dot.
• B. Class selectors are prefixed with a hash (#).
• C. Universal selectors apply styles to all elements.
• D. Element selectors use double quotes.

Answer: (C)

The statement about universal selectors accurately describes their function in CSS. Universal selectors are denoted by an asterisk (*) and apply a style to every element in a web document, making it a very broad way to apply CSS rules. For instance, if you declare a universal selector to set the font size, it will affect every element on the page unless overridden by more specific selectors. The understanding of how various types of selectors function enhances your ability to structure CSS efficiently. For example, while class selectors begin with a period (.) and id selectors start with a hash (#), this knowledge is crucial when writing styles. Element selectors refer to specific HTML tags, and quotes are not required in their syntax. Being familiar with these distinctions is essential for mastering CSS and correctly applying styles for web design.
