CSS azimuth Property

The CSS azimuth property is part of CSS aural content programming. It is used to specify the -360° to 360° horizontal direction a sound is coming from. Certain speaker systems and headphones have the ability to render surround sound, and some people have software that can read the text aloud to them for an audible rendering of document content. Use azimuth together with the elevationproperty to create a 3D sound stage environment with different voices coming from different directions. The elevation property controls the vertical plane of a sound while azimuth controls the horizontal plane of a sound.
TIP: Text-to-Speech software must be CSS-aware for this audio effect to work. It is only handy for screen readers and text-to-speech systems that are CSS-aware, which not many are. If the text-to-speech software you are using is not CSS-aware, the property will render no direction effect to the text spoken.

CSS CODE EXAMPLE

<style type="text/css">
h1 { azimuth: 70deg; }
h3 { azimuth: behind left; }
p { azimuth: left; }
</style>
<h1>This is header1 content</h1>
<h3>This is header3 content</h3>
<p>This is my paragraph content.</p>

 

This is header1 content

This is header3 content

This is my paragraph content.

far-right
Keyword for a "60deg" position, when used with the 'behind' keyword makes "120deg".
right-side
Keyword for a "90deg" position.
