PROBLEM SOLVED. So, when I went home, I signed in and noticed that all the wonkiness was gone, but then I got to work this morning and it was still there. I tried on another computer and the wonkiness was gone there, too. So I cleared my cookies – I had only been clearing my cached images and files before, not the cookies – and voila, it is back to normal.
Thank you everyone that helped! I am assuming it was the stylesheet that Kim gave me that did the trick, but I had no clue because my cookies weren’t clearing whenever I cleared my cache.
