Hi,
open this CSS file:
/templates/flexible_asymmetric/css/custom.css
and include this CSS rule:
#vmCartModule .product_row:nth-child(1):after { display:none;}
This will eliminate the space completely. You should better put some space between them, 10px or something
To do it, include this CSS rule:
#vmCartModule .product_row { margin-bottom:10px;}
Regards,
