text-stroke
is an experimental CSS property in webkit, (Safari 4 and Chrome). It is only supported in these browsers. text-stroke takes a length value (the width of the stroke), and a color valur (the color of the stroke.)
webkit also proposes a new fill-color
property, which specifies the color of the non stroked text. While this seems redundant given the color
property of CSS, this enables you to specify a fill color that would otherwise make text illegible if text-stroke wasn't supported.
