The specification for the article
element says:
The
article
element represents a component of a page that consists of a self-contained composition in a document, page, application, or site and that is intended to be independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.
So, if I'm building a website where, in its home page, I have cards that are clickable and leads you to the article page, would be better - in semantic - if this card would be a section
or an article
element?
