When you head to Modula > Gallery ‘A’ > Settings > Style, you’ll see the above options appear. Each of them has a little tooltip so you can quickly reference what each of them does in case you forget. The border size will allow you to choose the size of your border around your images (like an outline). The shadow will allow you to add a shadow effect to the images in your gallery. Beyond that, they can be configured to your liking by using the sliders to adjust size and using the color pickers to choose the respective colors. If you wish to disable the border, simply set the size to 0 and if you wish to disable the shadow simply set its size to 0.
