Navigating through "Stimmen" at subpage "Was ist Coding da Vinci"

[ikyriazi]

At https://codingdavinci.de/de/was-ist-coding-da-vinci there is a section with tiles of people talking about their CdV-experience (s. image):

Unfortunately when navigating through the tiles (= when clicking on the arrows right or left) the tiles shift to the top of the browser window and the arrows are not visible anymore. Could you fix it, so that we can navigate to the right or left withough any vertical movement and the arrows remain always visible?
