Image Jux Slider - Change color of slider bar

21cccs's picture


I created an image slidker (, but since my image is white and the slider is also white, my students don't realize it's an interactive activity - they just think it's one big picture. 

Would love a way to change the color of the slider, or outline it, or some what to make it stand out against white images.

Image Juxtaposition not working

My Image Juxtaposition content types that I create aren't working in Firefox--when you click and drag nothing happens, or if it does work there's a big delay. Interestingly, the demo is working fine on Anyone else experiencing this? I'm using it for a translation exercise--overlaying a translated passage over one in the target language.
