The CSS mod corrected the issue with one module position in content top spanning the entire top of the content area. However, it broke the design when two of the contenttop positions need to be adjacent to each other. For example, on the home page, the slideshow in position contenttop b should be next to the "INTRODUCTION" image in contenttop a. Instead, it appears as each is assigned 100% and they are stacked vertically.
