Synopsis
Inherited: Yes
For aural style sheets, sets the dynamic range (softness/loudness) of the spoken element. Because normal speech has inflections that prevent an absolute volume to apply at all times, the volume attribute sets the median volume.
CSS Syntax

Value
A volume number value is any number. A
value of zero should represent the minimum audible level for the
equipment and ambient noise environment; a value of
100 should represent the maximum comfortable level
under the same conditions. A percentage
value is calculated relative to the parent element’s volume
attribute setting. Alternative settings include the following
constants (and their representative values):
silent (no sound) | x-soft (0)
| soft (25) | medium (50) |
loud (75) | x-loud (100).
Initial Value
medium
Applies To
All elements.
