114
115<p>The CSS 2 property <code>text-shadow</code> is supported in
116Safari since version 3 (also available for Windows), Opera since 9.5, Firefox since 3.1, Konqueror and iCab.
117Future versions of Google Chrome should also support <code>text-shadow</code> because Chrome is based on WebKit,
118the rendering engine behind Safari. Internet Explorer 8 does not support such text shadows
119(except for some DirectX image transform filters).</p>
