HTML 5 <hr> tag
The <hr> tag is used for specifying a
horizontal rule in an HTML document which should indicates a paragraph-level
thematic break. For example, if there is a scene change in a story, or a
transition to another topic within a section of a reference book.
Example
<!DOCTYPE
html>
<html>
<head>
<title>Example
of hr Tag</title>
</head>
<body>
<h3>This
text is above the horizontal rule.</h3>
<abbr
title="This is
horizontal rule"><hr></abbr>
<h3>This
text is above the horizontal rule.</h3>
</body>
</html>
Output
HTML 5 <iframe> tag
The <iframe> tag is used to specify an inline
frame which allows you to embed another document within the current HTML
document. This is also referred in HTML 5 specification as a "nested browsing
context".
Example
<!DOCTYPE
HTML>
<html>
<body>
<iframe
src="http://www.dotnetheaven.com"
width="400"
height="300"></iframe>
</body>
</html>

Note:
In previous versions of HTML, you have to create "fallback content" by placing
content within the opening and closing
<iframe>
</iframe>
tags but in HTML 5, the code><iframe> element never has fallback content.
