What approach prevents a fixed header from overlapping page content?

• A. Add padding-top equal to header height
• B. Hide content below header
• C. Increase header height
• D. Use sticky header

Answer: (A)

When a header is fixed, it sits on top of the page and is removed from the normal document flow, so the content starts right under it unless you create some space for it. Adding padding-top on the main content equal to the header’s height reserves that space, pushing the content down so it never sits under the header as you scroll. For example, if the header is 60px tall, give the content container padding-top: 60px. This keeps the header visible while the page content remains fully accessible. Hiding content isn’t a proper solution, and increasing the header height would only make the overlap worse. Using a sticky header is a different technique; it can still require offsetting content to avoid overlap.
