Now the animation used here don’t seem to generate extra divs like that:
Do note current webpage doesn’t have any longer the layout, hence I’m linking to Wayback machine mirror. This is an example of the classes used in the animations
<div class="split-item-image split-item-image-fill reveal-scale-up is-revealed" data-reveal-container=".split-item" data-reveal-delay="200"><img src="/web/20201123092442im_/https://magicflow.io/static/images/landing/feature_2.png" alt="No more guesswork" width="528" height="396"> </div>
So bottom line do you happen to know which library uses those animation classes or do you recommend a library which doesn’t generate problems with the layout?
I did google but haven’t tested yet all of the mentioned here CSS Animation Libraries | CSS-Tricks
