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%.
