HTML hr tag

The HTML <hr> tag is used for specifying a paragraph-level thematic break in an HTML document.

A a paragraph-level thematic break could be a scene change in a story, or a transition to another topic within a section of a reference book.

Prior to HTML5, the <hr> tag was used purely for presentational purposes (i.e. to create a horizontal rule). From HTML5 however, it was given a specific semantic purpose (to represent a paragraph-level thematic break).

<p>Here is a horizontal rule...</p>
<hr />
<p>...did you notice the horizontal rule?</p>

Eg. :

Here is a horizontal rule…

…did you notice the horizontal rule?
