How to change the number of items per row in products grid?
How to modify magento 2 to show 3 items per row in product grid instead of the default 4? I tried to play with /var/www/magento2/vendor/magento/theme-frontend-luma/Magento_Catalog/web/css/source/module/_listings.less but nothing changed. I've restarted apahce2... I have flushed magento2 cache ... I have deleted all folders under /magento2/var/cache ... but still showing 4 items per row!!!
