And why is it not possibe to make the window smaller?
like
[[include include:video-left
|width=760px
|video=<iframe width="760" height="480" src="//www.youtube.com/embed/Gms5YnDi_tc" frameborder="0" allowfullscreen></iframe>
|text= Favourites
]]
of course - I had to adjust the height in teh same relation - could be it is wrong…
