Juxtapose
Juxtapose helps storytellers compare two pieces of similar media, including photos, and GIFs. It’s ideal for highlighting then/now stories that explain slow changes over time or before/after stories. Web-based Juxtaposes are interactive. They can also be used as animated GIFs on social media.
