"section" has semantics, indicating content grouping with themes, usually including titles, which helps to build a document outline; 2. "Div" has no semantics, only provides packaging for styles or scripts, and does not affect the document structure; 3. "section" should be given priority to express meaningful page areas, and "Div" should be used to deal with layout or visual needs; therefore, "section" should be used when the content forms an independent logical part, otherwise "Div" can be used to complete style or functional grouping.
