Put twenty/twenty into carousel

[QuentinLf]

Hi everyone,

I’m a beginner in html website creation. I managed to make an html code to create a slider that shows a before/after picture. I put the images and js and css script in my dropbox to generate a url and call it (see below). I also managed to make an html code to create a carousel with images from my computer (see below). My problem is that I still don’t understand how to combine the two html codes and therefore make a carousel not with still images, but with before/after slider.

Can someone help me?

Thanks a lot.
