Hi,

please have a look at:

Overlapping Blocks

and

Overlapping Blocks 2

You can see a very thin grey line in the bottom of block one from block two. I have reduced the distance, went to a negative one, from block one to two and saw this overlapping witht he grey shade.

Then I have set the background of block two to transparent again in the template and nothing changed.

Any idea for help?

Thanks!
