I'm using Moodle 2.6 with the Essential theme. My client wants the center column of the page to have a white background, which I added. However, the border around each module/area in that column is funky. I keep trying to make it so there is the same amount of white edge around all sides of the border, but it's not working. See how the border on the left has white outside of it, but there is no real border/white area on the right side of the column. There should be the same amount of white on the right side as there is on the left. What do I need to do?
Here's a screenshot:
