CSS ELEVATION

In an optimal listening environment, the soundstage is considered to be parallel to the floor, with origin point at the listeners head. This property specifies the vertical angle off of the soundstage plane giving up/down angle references as a location for a referenced element. Zero degree references are forward on the soundstage plane, with positive angular values being upward, and negative values being downward. This property only describes the desired end-user effect and does not specify how it is produced.

Example
1
p.high { elevation: 45deg }
1
<p style="elevation: 45deg">Some text</p>

Possible Values

inherit: Explicitly sets the value of this property to that of the parent.
below, level, above, below: Same as ‘-90deg’
level: Same as ’0deg’
above: Same as ’90deg’
lower, higher, lower: Subtracts 10 degrees from the current absolute or inherited elevation.
higher: Adds 10 degrees to the current absolute or inherited elevation.
[angle]: Specifies an angle, between ‘-90deg’ and ’90deg’. ’0deg’ references straight ahead/forward on the soundstage plane (level with the listener.) ’90deg’ is directly overhead while ‘-90deg’ is directly below.
