HTML Paragraphs
A paragraph is defined with the <p> tag. Browsers automatically add a single blank line before and after each paragraph. You cannot control the output by adding extra spaces or blank lines inside the HTML source — the browser ignores them.
Line Breaks and Horizontal Rules
Use the <br> tag when you need a line break without starting a new paragraph, such as in a poem or address. The <hr> tag creates a thematic break — a horizontal line — between sections of content. Both are void elements and need no closing tag.
