I do now in fact have comments (and therefore welcome any answers to the previous questions). I am quite proud of having figured out on my own how to add them (not that it was complicated, but still). I have not yet, however, figured out what code to use to make them appear in a different color than the background. Right now they're the purple spot next to the random pink line under the post.
Never fear, blog, I will strive to amend this posthaste.
