Have you ever seen a straight horizontal line in webpages separating two paragraphs. I bet you have seen.
And using the hr tag a straight horizontal line can be drawn in a webpage.
<html> <body> <p> First line. </p> <hr> <p> Second line. </p> </body> </html>
So, if you look at the above output, a horizontal line is inserted in the webpage.
The horizontal line is inserted because of the hr tag we have placed in our code.
<hr>
HR tag stands for Horizontal Rule.
