Separating the space into smaller containers gives you more control over each area, and that's what the <div> tag does on a webpage. It acts like a container that separates a webpage into sections, the most common being the header, navigation, content, sidebar, and footer.^[1]By adding other tags, you can style each section differently without changing the look of other sections. Keep in mind that it's a block-level tag, meaning that it separates its section from the rest of the page with line breaks.
