Sorry to do this the unprofessional way but I have a problem with my blogger lay-out and I can find the answer anywhere. As you might have noticed, my left column tends towards the post section. Actually if I upload a big image you can see that it even overlaps the post section a bit. The right column on the otherhand acts completely normal. I tried to find the problem in my HTML but I wans’t able to find anything. Also I could not find any tutorials on this. So if there is anyone who knows how I might solve this they would be a great help.
PPS: Problem solved!
