I'm trying to set the slider height on my home to be 100% minus 100px, so i.e. if the window height is 800px, the slider will have 700px and below you'll see the first 100px of the next div. Then, when you resize the window to 600px, the slider height will scale down to 500px and you'll still see the first 100px of the div below.
You can see this working on apple.com
The macOS / iOS / WatchOS divs are always shown with the same height, and if you resize the window only the slider gets smaller.
Hope there's a way to do this without crazy code
