Backgorund images/ color stuff

Spent exactly an hour tonight. Entire lesson was a repeat of knowledge I've already aquired, but the presentation and hands on learning made the review engaging and an overall good refresher. Strong signs of a great teacher. I do have one question so far (I finished up to 5.4 this evening). For problem 5.2, I am curious as to why we had to increase the specificity of the anchor to change the border color. I'll finish the lectures and check the discussion tomorrow for some insight.
