The HR tag creates a horizontal rule (see below)

Here are some of the Deprecated HTML4.01 attributes that are no longer supported via HTML5.

• align=
• color=
• noshade
• size=
• width=

Here is a Horizontal Rule with align="center" color="#FFFFFF" noshade size="10" width="50%"

and the same HR with the noshade removed

It's better to use CSS to format the HR properities

• hr {
• border: 0;
• color: #rrggbb;
• background-color: #rrggbb;
• height: 1px;
• width: 75%;
• text-align: left;
• }

Here is a Horizontal Rule with inline CSS via the style attribute border: 5; color: #006699; background-color: #ffaa33; height: 15; width: 50%; text-align: right
