<h1>The backface-visibility Property</h1>
<p>This example shows the back face of two div elements.</p>
<p>This div element has "backface-visibility: hidden", and the back face of the div element is invisible:</p>
<div id="div1">DIV 1</div>
<p>This div element has "backface-visibility: visible", and the back face of the div element shows a mirror image of the front face:</p>
<div id="div2">DIV 2</div>
<p><strong>Note:</strong> The backface-visibility property is supported in Safari with a webkit prefix.</p>
