Please help me Suggest a Universal Systems Model that would help to solve one of the following problems:

the creation of a new Olympic sports park.

cleaning up of an oil spill.

writing a book/piece of music.

What will the inputs and the outputs be? What are the processes? Ensure that you describe all the different types of outputs. Also, include the feedback in this model.

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)
