How To Change Default Grid

[Kristof111]

I want to change the default grid so I can have like 6 products on the same line in stead of 4 or 3.

This is what I've done so far:

I changed some code in the product-list.tpl 

<li class="ajax_block_product{if $page_name == 'index' || $page_name == 'product'} col-xs-12 col-sm-4 col-md-2{else} col-xs-12 col-sm-6 col-md-2

 

and: 

 

{*define number of products per line in other page for desktop*}

{if $page_name !='index' && $page_name !='product'}

{assign var='nbItemsPerLine' value=6}

{assign var='nbItemsPerLineTablet' value=2}

{assign var='nbItemsPerLineMobile' value=3}

{else}

{assign var='nbItemsPerLine' value=6}

{assign var='nbItemsPerLineTablet' value=3}

{assign var='nbItemsPerLineMobile' value=2}

 

I thought this would be enough but nothing changed..

Can someone help me?
