The elevation property sets where the sound should come from vertically. The possible values are as follows −
- angle − Specifies the elevation as an angle, between -90deg and 90deg. 0deg means on the forward horizon, which loosely means level with the listener. 90deg means directly overhead and -90deg means directly below.
- below − Same as '-90deg'.
- level − Same as '0deg'.
- above − Same as '90deg'.
- higher − Adds 10 degrees to the current elevation.
- lower − Subtracts 10 degrees from the current elevation.
You can try to run the following code to implement CSS elevation property −
<style>
<!--
h1 { elevation: above }
tr.a { elevation: 60deg }
tr.b { elevation: 30deg }
tr.c { elevation: level }
-->
</style>
