Watching the video for Sliders. In the video, he adds a container to the slider and then brings the slider down via padding. After he does this the container is visible where he put. When I tried this, it seemed as my container did the opposite as it is still connected to the top. No idea what I did wrong.
Some UI might have changed, however, simply adding something in the container like text/header will fix it, as a container is not supposed to be left empty anyway.
