This post is the first topic I discussed in my jam session presentation at Fronteers 2012. It’s about the drop-shadow filter. You may have looked at it and thought “this is pretty much the same thing as a box-shadow” right? Well, not exactly. The big advantage of the drop-shadow filter is that it acknowledges the outline and transparency of an element.
Yes, it’s an experimental property, and yes, it’s only supported in some WebKit browsers now. But according to caniuse.com there’s already 32.51% of web users with support. And since it’s usually a decoration type of enhancement you can start using this today.
