Magento - 删除1.8上的“ShortDescription”Div

A Magento & php noob here. I'm trying to removed the Short Descriptions from a store as they are unnecessary/unneeded. I've adjusted the attributes to disable them.

It seems to leave a white space similar to a
although i can't find any in the code.

I've been trawling google and forums but all the fixes are for older outdated version and do not work.

I've tried to removed the nl2br tag but still it has no effect.

Current website is here: www.petwholesale.co.uk/magento/

Is there anyway to force the div not to load? I'm fairly new to all this and it's rather confusing!

Thanks, Max

There is a large amount of padding on the bottom of the list item. The following css section is the area that should be reduced.

.col2-left-layout .products-grid li.item, .col2-right-layout .products-grid li.item {
    padding: 0px 20px 60px 0;
    width: 200px;
}

But even then the reason that the Add to cart button appears to display after this padding is because of the position absolute on the action div.

.products-grid .actions {
    position: absolute;
}
