A horizontal rule created by the tag <hr /> creates a horizontal line that can can be used to break a webpage into sections. A horizontal rule is a block-level element, which means it has embedded carriage returns before and after, placing it on it's own line. Shown below is a generic horizontal rule.
<hr />
The horizontal rule has several attributes that allow you to control its appearance.
| Attribute | Meaning | 
| align | Alignment on page, left, right, or center. | 
| color | Color of the rule. | 
| noshade | Normally horizontal rules display with 3D shading. | 
| size | Thickness in pixels. | 
| width | Width in pixels, or as a percentage of document width. |

The code above creates the horizontal rule shown below.
I know this section should be about html only, but the example below shows what you can do by adding a little style to a horizontal rule.
<hr align="left" size="8" width="200" style="border-style:outset; background-image: url('bg000017.gif');"  />
If you're using the Firefox browser, you'll see a beautiful rainbow colored three-dimensional rule. If your using Internet Explorer, you'll see a three-dimensional gray rule.
