Change size header ipad and enable "play-button" on mobile/tablet

Hi There,

We’ve just launched our new website: http://www.vechtenveld.nl
Absolutely very happy with the theme, it’s beautiful!

There are 2 things left I need some help with. Hope you can help me…

1) when viewing the site on a mobile phone (iphone 6), the header is smaller and the logo is on the top left position, also very small. I would like to have the same view for an ipad/tablet. The header is just to big and you miss to much information on your screen. I did find something about making the header smaller, but then the logo is still in the same position and size. Cab you provide me the code I should use to make the header/menu the same way it works on the phone?

2) I already know about the youtube background video and why it cannot autoplay and that you see a still of the video and a play button. But why does this play button not work? It would be nice if you can watch the background video bij push the play button.

Looking forward to your reply and many thanks again!
