Fitting Length to Screen

I would like for the media player to display full length on mobile but i’m unable to. Does this mean that since mobile devices have different heights, i won’t be able to have a one-size-fit-all solution?

If you’re using Bubble’s new responsive engine, this tutorial can help (it’s not the exact same, but the principles still apply):

Thank you, I’ll have a look at this.

So do you think I can achieve this using the old responsive engine?
