## Example

Try it yourself!

## Definition and Usage

The <hr> tag creates a horizontal line in an HTML page.

## Browser Support

The <hr> tag is supported in all major browsers.

## Differences Between HTML and XHTML

In HTML the <hr> tag has no end tag.

In XHTML the <hr> tag must be properly closed, like this: <hr />.

All "presentation attributes" of the hr element were deprecated in HTML 4.01, and are not supported in XHTML 1.0 Strict DTD.

## Tips and Notes

Note: The hr element renders differently in different browsers.

## Optional Attributes

DTD indicates in which DTD the attribute is allowed. S=Strict, T=Transitional, and F=Frameset.

Attribute | Value | Description | DTD
--- | --- | --- | ---
align | center left right | Deprecated. Use styles instead. Specifies the alignment of the horizontal rule. | TF
