I now have an idea how to create the requiered space:
I added in the css class of the columns “padding-bottom” with the value of the height from the video.
The problem now is how to get the value of the height from the video in the css file as a variable.
I tried useing someething like this:
var height = document.getElementById(‘element’).offsetHeiht;
but first of all I would have to add an ID to the video and I also have no idea how to connect a Javascript comment to CSS
