Youtube codes within Impreza

With Wordpress and Impreza I built openjeboek.nl. I included Youtube clips. I would like to influence their appearance. I found several commands, like Rel, Autoplay, Loop and Showinfo on https://developers.google.com/youtube/player_parameters#disablekb. I learned they work well with

I tried several situations with ? and & and ;, but nothing seems to work :-(.

How can I include these Youtube codes in Impreza?
