This should be in C++ please Modify the linked list implementation to use a dummy node for the past-the-end position whose data member is unused. A past-the-end iterator should point to the dummy node. Remove the container pointer in the iterator class. Reimplement the member functions so that they have the same effect as before.

None of the above. i

Well, this code would box the whole body of an html document. by using the relative value for position, you are telling it to position relative to its normal position, which the top left corner is at (0,0). by using left: 50px, you are telling the box to set the left margin  edge to 50px and by using top: 50px, you are telling it to set the top margin edge to 50px. by doing this shifting, the top left corner of the box, which is at (0,0) would be positioned at (50,50)
