All Elements have one of two position settings:
A relatively positioned Element behaves as a statically positioned Element, except you assign it an offset from its original static position. For example, you can shift an Element 20 pixels to the left of the position it would appear in if it were statically positioned or shift it 100 pixels down.
For absolutely positioned Elements you choose their offset from the outer limit of the Box element they are in. Absolutely positioned Elements may overlap other Elements.
