Question

tags in HTML5.

Answer 1

It depends on your content.

For example, a list of recent blog posts could be a section containing several article (example 1), a complex blog post could be an article with several section (example 2), a blog post with comments could be an article with a section and several article (example 3).

How to decide when to use which? Easy:

1. If you need a sectioning content element, start with section.
2. Check if the content matches the definition of nav. If yes, go with nav, else:
3. Check if the content matches the definition of aside. If yes, go with aside, else:
4. Check if the content matches the definition of article. If yes, go with article, else:
5. Stay with section.
