I recall DrByte strongly suggested not to mess with that line (around 400 correct?), and to edit in case the lines around 180
PHP Code:
// set css classes for "row" wrapper, to allow for fluid grouping of cells based on viewport
// these defaults are based on Bootstrap4, but can be customized to suit your own framework
if ($product_listing_layout_style === 'fluid') {
$grid_cards_classes = 'row-cols-1 row-cols-md-2 row-cols-lg-2 row-cols-xl-3';
// this array is intentionally in reverse order, with largest index first
$grid_classes_matrix = [
'10' => 'row-cols-1 row-cols-md-2 row-cols-lg-4 row-cols-xl-5',
'8' => 'row-cols-1 row-cols-md-2 row-cols-lg-3 row-cols-xl-4',
'6' => 'row-cols-1 row-cols-md-2 row-cols-lg-2 row-cols-xl-3',
];
