CSS3 text-shadow rocks, but it doesn’t work in any version of Internet Explorer, including IE9. While it is impossible to replicate all text-shadow effects in The Browser That Likes To Be Difficult, there are some ways to emulate this effect without JavaScript using Visual Filters, even when ClearType is enabled.
