The <p> tag is used to define a paragraph of text, while <h1>–<h6> are heading tags that define section headings. Headings represent a document’s structure and hierarchy, where <h1> is the highest-level heading (most important) and <h6> is the lowest-level heading (least important).
Headings (<h1>–<h6>) improve accessibility and SEO by providing structure.
Paragraphs can follow headings to add descriptive content.
