## HR - horizontal rules

Horizontal rules may be used to indicate a change in topic. In a speech based user agent, the rule could be rendered as a pause.

`HR` elements are not containers so the end tag is forbidden. The attributes are: `ALIGN`, `NOSHADE`, `SIZE` and `WIDTH`.

align
  This determines whether the rule is placed at the left, center or right of the space between the current left and right margins for `align=left`, `align=center` or `align=right` respectively. By default, the rule is centered.
noshade
  This attribute requests the user agent to render the rule in a solid color rather than as the traditional two colour "groove".
size
  This can be used to set the height of the rule in pixels.
width
  This can be used to set the width of the rule in pixels (e.g. `width=100`) or as the percentage between the current left and right margins (e.g. `width="50%"`). The default is 100%.
