Enfold 2017 Demo – Layer Slider: Max height but responsive

Hi there,

the LayerSlider for the homepage of the Enfold 2017 demo has a fixed max-height (850px). When I use the exact same setting for my LayerSlider (responsive, Canvas width 1410, Canvas height 850) it expands beyond that while resizing the window. How can I set it to 850 max but width always 100%, like in the demo?

Thanks in advance
Henning
