Hey guys! I have a difficulty to remove the space between 2 div or table and between the 2 content block as well. Please see the screen shot attached. It look just fine in the normal HTML web page but after converted to the concrete5 theme the space will appear. Thanks!
You haven't attached a screenshot, but chances are this is margin or padding in the concrete theme's css. Have you tried Firebug in Firefox to discover what's causing the gap? That's the first thing I'd try.
