Responsive Design, CSS Grid, HTML5, JavaScript

My main question after doing this challenge is how do I know which HTML tags to use aside from div? From what I understand, div has no special meaning and is used as a container for content, but what about other tags like article? How do I know when is it proper to use these other kinds of tags?

Any and all feedback is welcome even if it doesn't relate to the question above! I really hope to continue improving my web design skills and I'd be more than happy to hear any suggestions or comments on how to do so :)
