It is used to define a section in a document when there is no other more specific semantic element to represent it.
Typically, although not required, it usually has a header (<h1>-<h6>) that is used to identify each <section> in the document.
If its content can make sense in isolation, outside of the document, it is more appropriate to use an <article>.
It should not be used as a generic container, for that the <div> already exists. The <section> should be used only for those blocks that we want to appear in the outline of the document.
It has an implicit ARIA role region only if it has an accessible name assigned with aria-labelledby, aria-label or title, in that order. Otherwise, it has no role.
