I have a question that drives me nuts. When I use box-shadow on an .png image, everything works normally although it forms a square around the image. To solve this we can use drop-shadow, which indeed follows the form of the image. However I can move the shadow left, right, up & down making it more or less blurred. But I can't find out how to spread the shadow! It seems like the 4th value cancels everything out of shadow.
The box shadow:
-webkit-box-shadow: 0px 0px 130px 150px rgba(39,21,6,1);
-moz-box-shadow: 0px 0px 130px 150px rgba(39,21,6,1);
box-shadow: 0px 0px 130px 150px rgba(39,21,6,1);
The drop shadow:
filter: drop-shadow(0px 130px 150px rgba(39,21,6,1));
