HTML Headings & Paragraphs
Headings
HTML has six levels of headings: <h1> through <h6>. h1 is the most important (largest) and h6 is the least important (smallest).
Use only one h1 per page — it is important for SEO and accessibility.
Paragraphs
The <p> tag defines a paragraph. Browsers automatically add space before and after each paragraph.
Line Break & Horizontal Rule
<br>— Inserts a line break (no closing tag needed)<hr>— Inserts a horizontal divider line
