I have a problem with the responsiveness of vimeo embeded videos.
It's easy to embed the videos via iframe and for normal screens it works well.
But when I change the screen resolution e.g. while viewing on my iPhone the embeded vimeo videos get an ugly letterbox. (Black bars at the top and the bottom.)
I tried several other methods to embed the vids. But nothings seems to work.
Would appreciate if somebody is able to help me. :)
