Paragraphs

The <p> tag defines a paragraph. It is the most common element for text content.

Characteristics

1. Block-Level Element: A paragraph always starts on a new line and takes up the full width available.
2. Automatic Margins: Browsers automatically add white space (margin) before and after a paragraph.

Behavior with Whitespace

HTML ignores extra spaces and line breaks within the code.

• If you type 10 spaces, the browser displays only 1.
• If you press "Enter" 5 times in the code, the browser displays it on the same line.

Example of Whitespace collapse:

<p>
  This      text       contains
  many       spaces     and
  lines.
</p>

Output: "This text contains many spaces and lines."

Line Break Tag <br>

To force a line break without starting a new paragraph (and without extra margin), use the <br> tag. <p>Line 1<br>Line 2</p>

Horizontal Rule <hr>

The <hr> tag defines a thematic break in content, typically displayed as a hormonal line. Used to separate chapters or topics.
