I saw a post from 2018, I've created a mask and attached it to one of the images with a code snippet from the post, but unsure how to animate and preview/test based on mouse/touch position. I would like to create an HTML5 ad (800x250) where the viewer can slide between before and after pictures as they please. I'm not familiar with coding, but hoping there may be a simpler way to achieve this since 2018.
The images are nestled on the right side of the document, if that matters.
