Any article from around 2011 or earlier will mention them in discussion of fancy styling techniques, but in most cases they can now be dropped in favor of the plain CSS standard property. Users of browsers other than IE tend to keep up to date and old instances of Chrome or Firefox are a small minority, while IE8 still has a measurable user base, and for some audiences, even older versions need to be supported.
