HTML Paragraphs

Paragraphs are defined with the <p> ... </p> tag.
Paragraphs may contain text and inline elements. They are block elements, but they may not contain other block elements, including other paragraphs.
The length of the displayed text will be adjusted by the opening size of the browser.
Browsers automatically add an empty line before and after a paragraph, so, the distance between two successive paragraphs is of two lines.


- Example:
<!DOCTYPE html>
<html>
<head>
<title>Document Title</title>
</head>
<body>
<h4>Example Paragraphs</h4>
<p>Paragraph 1</p>
<p>Paragraph 2</p>
<p>Paragraph 3</p>
<p>Paragraph 4</p>
</body>
</html>

Line Breaks - <br>

The <br> tag inserts a line break in the content, it allows you to control where to add new line breaks, to force the beginning of a new line at a particular poinnt.

- Example:
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<h1>Be Happy</h1>
<p>The Peace is Good.<br>
Line 2<br>
Line 3<br>
... </p>
<p>The smile brings joy.</p>
</body>
</html>
- <br> is an empty element, but may contain attribute (id, class, style).
Example:
<br id="idb">

Horizontal rule - <hr>

The <hr> tag creates a horizontal line in an HTML page.
The <hr> element can be used to divide a web page into different horizontal areas.
The <hr> tag is a block level element, and it uses the standard attributes: id, class, style.
With the CSS background proerty you can define the line color, and with the height property you can set the line thickness.


- Example:
<!DOCTYPE html> 
<html> 
<head>
<title>Document Title</title>
</head>
<body>
<h1>Page Title</h1>
<p>Paragraph 1<br>
Line 2<br>
Line 3<br>
... </p>
<hr>
<hr style='background:#1111fe; height:3px; width:50%;'>
<p>Paragraph 2</p>
</body>
</html>
