About Juxtapose Slider

The slider is created using the free, open source, JuxtaposeJS. Its a handy tool that helps storytellers compare two pieces of similar media, including photos, and GIFs.

It was produced by the Northwestern University Knight Lab, created by Medill student Alex Duner.

JuxtaposeJS works on all devices. All you need to get started are links to the images you’d like to compare.
