Number of products per row
To change the number of products per row, you need to go to list.phtml
folder structure: /app/design/frontend/default/jewelry-store/template/catalog/product/list.phtml
And change line 96 <?php $_columnCount = 3 //$this->getColumnCount(); ?>
Change the number to amount per row you want. You might have to change widths in the CSS which would be under product-boxes.
