Decrease the "height margins"

I'd like to decrease just the spaces "height margins" and if you can tell me how to center the "product category block", remove "icon image" like is showed in the image. I'd be so happy but with just changing the spaces I'd be ok. My web is http://3bikes.cl/

Please add this code to override.css and make sure override is enabled in template settings.

Code: Select all

#gkMainbodyBottom .productdetails div.spacer,
#gkMainbodyBottom .productdetails div.vm-price-value {
    text-align: center;
}


This will center products information in boxes so it will look centered. Rest of the requests looks to be completed.
