Section

The HTML element represents a generic section of a document (a thematic group of content, typically one with a heading). This element must not be a descendant of an <address> element. If it makes sense to separately syndicate the content of a <section> element, use an <article> element instead. Do not use the <section> element as a generic container; this is what the <div> element is for, especially when the sectioning is only for styling purposes. A rule of thumb is that a section should logically appear in the outline of a document.
