The semantic tags don't cause any special appearance by themselves, but CSS can target them to apply styling. They also assist automated data collectors (robots) to find significant parts of the page to classify and index the page for search engines.

You can certainly write code without them, but anyone examining your pages might think they were legacy code developed before the semantic tags became the modern standard.
