volume | NN n/a IE n/a CSS 2
| Inherited: Yes
For aural style sheets, this 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.

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).
