Item size in gallery block (Exhibit)

My items in the gallery block display as thumbnails. Where in css could I change it to display them in full size (rectangular)?

The “gallery file size” option for the gallery block lets you choose between showing squared-off thumbnails or “normal” thumbnails with the aspect ratio unchanged from the original. You shouldn’t need to do anything yourself with CSS, just change that setting.

Thank you John! I only noticed after I posted it that the layout can be changed:-)
