Question 1: Precisely which CSS property(s) do you modify to change the left indentation of the whole list?
To change the left indentation of the list, the padding-left of the ul block should be modified.

Question 2: What CSS property can you use to change where the bullets are drawn relative to the li blocks?
The position: relative property and left: # px allows modification of where bullets are drawn relative to li block.

Question 3: To adjust the vertical space between the list items to make the list more or less compact, what CSS property of which blocks would you modify?
The vertical space is determined by the top and bottom margins on the li block. Question 4: How did you fix the collapsing border of the parent block problem?
To fix the collapse issue, I added overflow: auto to the parent block. This declares that the parent block must grow with the floating items inside.
