Document Structure
Semantic Article
Sections Give Content Meaning
A short article page uses semantic containers so the rendered page and accessibility tree have meaningful regions.
Program
Semantic HTML chooses elements for meaning first. The browser still renders ordinary boxes, but the document tree carries richer structure.

The heading labels the article for readers and assistive tools. Add the article body text.

The footer completes the semantic page regions.
