Q
How can you ensure that certain elements are hidden when printing an HTML page?

Answer & Solution

Answer: Option Option A
Solution:
You can ensure that certain elements are hidden when printing an HTML page by applying the display: none; property in a print media query (@media print {}). This CSS property removes the elements from the document flow and prevents them from being printed. By specifying display: none; for specific elements or classes within a print media query, you can exclude them from the printed output while still displaying them on the screen. The visibility: hidden;, opacity: 0;, and position: absolute; properties are not commonly used for hiding elements during printing.
