Herzog Dupont for YOOtheme Pro
Check out the custom elements for YOOtheme Pro created by the first YOOtheme Pro extension provider. They can easily be installed used on your website via a plugin. There are eight elements so far, all of them are included in the plugin: Toggle, Progress, Timeline, Counter, Flipcard, Image Comparison and Slideshow Grid. No fees, no ads, no subscription required. No additional JavaScript libraries such as jQuery are loaded by any of these elements (except for the Lottie element which, of course, requires the Lottie library).
