1. position: absolute is similar to position: relative, because it also makes the element it's applied to move away from its position in the normal document flow. 
2. position: absolute moves the element NOT relative to its position in the document flow, but rather relative to the top, right, bottom, and left EDGE OF THE PARENT ELEMENT
