This exercise overrules the external stylesheet with an embedded stylesheet in the <head> section. Using the margin-left command for the body element enabled me to push everything away from the image, rather than specifying margins for each of the elements.
With the border-bottom selector I was able to specify a different color for the line under h2 elements.
I wasn't happy with the way the listings looked so I put in a padding-left for ul of 25px.
