+**NOTE:**  Relative Position places an element relative to its current position.
+  * Moves the green box relative to its current position to 20px from the left and top without changing the layout around it.
+  * Thus, leaving a gap for the green box where it would have been had it not been position

+<WRAP info>
+**NOTE:**  Absolute Position has the offset relative to the parent.
+  * It will not leave any gap where it would have been.
+  * The position of the Green Box is based on its parent position (the dotted border).
+  * Thus, moving 20px to the left and bottom from the top-left origin of the dotted border.
