Use the Gallery Block whenever you want to show off multiple images in a cool new way, Avaris offers you this block to enable you to display your images in the best way possible.
Add gallery images
Click Add and start selecting the images you want to add to your gallery block, click on multiple images, then press Add to gallery.
Once you’re done a preview of the images you selected will show in that empty area below the select option, and you can Edit or Clear.
NB: To have gallery full width add it in Section block and uncheck “boxed content” option.
