One product per row in mobile version

Hello,

In the mobile version, within the WooCommerce pages with the products of each category, there are displayed 2 products per row. Because of this, the two buttons of the of a row straddle each other (see https://www.gliling.co.uk/wp-content/uploads/2016/08/Screenshot.jpg). Is it possible to modify the mobile version (to add a code in CSS or functions.php) so as to display only one product per row?

Thank you,

Nicolae
