Dynamic HTML: The Definitive Reference

Name

elevation — NN n/a IE n/a CSS 2

Synopsis

Inherited: Yes

Given a listener at the center of a three-dimensional sound space (like in a surround-sound-equipped theater), elevation sets the vertical angle of the source of the sound (for example, in a text-to-speech browser). See also the azimuth attribute.

CSS Syntax

elevation: angle | angleConstant

Value

Your choice of a specific angle (in degrees) or one of the five constant values. An angle value is any value in the range of -90 to +90 (inclusive) plus the letters “deg”, as in 90deg. The value 0deg is at the same vertical level as the listener’s ear. To set the angle above level, the value must be a positive value (45deg); below level requires a negative value (-45deg). Optionally, you can choose an angleConstant value from a library of descriptions that correspond to fixed points above and below level.

Value	Equals
above	90deg (directly overhead)
below	-90deg (directly beneath)
higher	+10 degrees from current
level	0deg (at listener’s ear level)
lower	-10 degrees from current

In combination with the azimuth attribute, you can place a sound at any point around a spherical surround-sound stage.
