Single gallery column for mobile

Hello,

Under the section 'Fine Art' of my website I have a series of photos that are set up in columns of 3 for desktop. Currently in mobile view the columns are set up for 2 columns. Is there some css code that would be able to show the photos in only one column for mobile only? I also would like to keep the spacing between images the same or similar. Thank you!

@media screen and (max-width:767px) {
	.gallery-masonry-wrapper.gallery-masonry-list--ready {
    height: auto !important;
}
figure.gallery-masonry-item {
    position: relative !important;
    width: 100% !important;
    transform: unset !important;
}
.gallery-masonry-item-wrapper {
    height: auto !important;
}
.gallery-masonry .gallery-masonry-item[data-loaded] img {
    width: 100% !important;
}
.gallery-masonry {
    padding-left: 0 !important;
    padding-right: 0 !important;
}
}

Thank you Tuanphan. Is there a way to get even height spacing between the images? I tried changing the "gallery-masonry-item-wrapper" height from 'auto' to around '550px' but the spacing is  uneven because the images have different heights. If not all good. Thank you anyway!!!!

Thank you tuanphan
