Hello,
Your issue is probably coming from your front-end template, using some CSS code like media queries will probably help you to solve it, here is a
thread
where you'll find an example :
You can do the modifications in the frontend css file via the menu Configuration > Display > CSS
Use the @media tags to change the width of the columns when the width of the page is less than xx.
ex:
@media (max-width: 767px) {
.hikashop_products .row-fluid .span4 { width: 49% !important;}
}
Here is some documentation about the layout customization:
