In a speech based user agent, the tag could be rendered as a pause.
|attribute name||possible values||meaning||notes|
|ALIGN||LEFT, RIGHT, CENTER||horizontal alignment of the rule||default is CENTER|
|NOSHADE||NOSHADE||requests the rule to be rendered in a solid color||as opposite to the traditional two-color "groove"|
|SIZE||integer||height of the rule, in pixels|
|WIDTH||width specification||width of the rule|
All of these attributes are deprecated in HTML 4.0
<P> Some text, followed by a basic (default) horizontal rule. </P> <HR> <P> Some other text. </P>
<P> A horizontal rule placed at the right and half the width of the document layout: </P> <HR ALIGN="RIGHT" WIDTH="50%"> <P> An example with all possible spices: placed at left, solid rule (no shading), height 5 pixels, width 100 pixels: </P> <HR ALIGN="LEFT" NOSHADE SIZE=5 WIDTH=100>
It is usually better to use a percentage specification than absolute number of pixels. The user's window might be very different from yours.
