You can view the site in question at 43realestate.com and see the problem between the yellow and blue sections as well as between the red and gray sections at the bottom. Specifically, the sections should flow seamlessly with the slants of the adjacent sections going in the same direction, just as it does between the blue and red sections.
This was a purchased theme and I re-ordered the sections, which is what threw the alignment off. I have attached the CSS file. It seems like the controls for these blocks starts at line 708, but I have changed the order of the border color elements and it does not do anything to fix the problem.
Your help is greatly appreciated and will help me stop banging my head against the wall!
