HTML Hypertext Markup Language

HTML uses tags to add different semantics to text.

H1 tag to Child, main title, add semantics to text, not font size.

H2 tag to child, level two heading.

H3 tags to children, ordinary paragraphs.

HTML is responsible for describing the semantics of the page, CSS is responsible for describing the page style, JS is responsible for describing the dynamic effect of the page.

HTML cannot center text, cannot change text size, font, color, but can add semantics to text through tag pairs
