Hi there , specify

.home-section{

  height: 70% !important;

}

in your theme options Styling Options -> Custom CSS

where the height percentage is actually the one you want

thanks

Hello, I was actually referring to the full screen video background. for fullscreen slider there is the maximage library handling the resizing so not possible to do it via CSS. Use full width parallax slider instead. Its height can be set using

ul.fullwidth-slider, ul.fullwidth-slider .caption-inside{

}

thanks
