White gap after adding Flickity inside page.

So I added Flickity on my website and used "top" to add it in the top of the page, but doing so created this weird white gap. I am not really experienced. I tried using margin and padding, but none of them used to make it work.

Start with the issue description and attached image, then reproduce the reported white gap with Flickity positioned at the top of a page. Done would require a confirmed cause and a fix or documented resolution, but the issue provides no source files, configuration, or test case.
