Which tag defines content aside from the content (like a sidebar)?

• A. <aside> tag
• B. <article> tag
• C. <section> tag
• D. <main> tag

Answer: (A)

If you want to mark content that sits alongside the main content but isn’t part of the central flow—like a sidebar, related links, or a pull quote—the aside element is the right choice. It signals to browsers and assistive technologies that this content is related but separate from the main narrative, so readers can skim or focus on the core material while still having access to supplementary information. This is different from the other semantic elements: an article is for self-contained, distributable content that can stand on its own; a section groups related content under a thematic heading; and the main element denotes the primary content of the page. The aside specifically handles content that is relevant but not essential to the main content.
