So right now you can see we've created this shadow by creating a sandwich of a blurred version of the rectangle, plus the solid version of the rectangle on top, but the shadow is uniform across the entire rectangle, making it look like the light source is directly above. If we want this to look like a true drop shadow, we need to shift the drop shadow either to the left, or to the right, and up or down so that it becomes a little offset from the original rectangle. That's exactly what we're gonna use feOffset for. FeOffset has two main attributes, dx and dy, this is a deviation in the x axis and the y axis, and this will take both positive and negative numbers.
