Photo Galeries - Display one column on Mobile Device and two colums on Desktop

Hi There

As per the title, I want to display one column on a mobile device and two columns on a desktop. The reason is the photos do not fit when displayed as one column on the desktop. They are sometimes too big to fit on the page.

I want the gallery type to be Grid: Masonary.

Website here: https://www.thriveboudoir.com.au/

I have searched and understand that this can be done, but I am missing something, as I can not get it to work when I try the code I found on the web.

Your help would be appreciated.

Thank you

Hi,
