Solved Gallery mobile view columns

Hello!

It seems when I switch to tablet/mobile the Gallery seems to look like this. The number of images and columns are even so there shouldn't be any white spaces left, but there is... The images are the same size (1080x800) and also added a custom line to PHP to make the thumbnails the same size.


add_filter( 'et_pb_gallery_image_width', 'custom_image_width' );
function custom_image_width($width) {
return '600';
}

add_filter( 'et_pb_gallery_image_height', 'custom_image_height' );
function custom_image_height($height) {
return '400';
}

add_image_size( 'custom-image-size', 600, 400, array( 'center', 'center' ) );

What could be the problem? Thanks in advance!

 

Sorry it works fine on mobile. Just the Divi preview shows it wrong.
