Transparent header

Hi there,

First i want to say congrats for the good themes you are making 🙂
I posted an presale question in themeforest comment 3 days ago asking about some small changes in the header, if it can be done and one of your team answered me that yes is possible.

So my question is: Is it possible to make the header (logo and navigation) to look like the header in this website: http://www.gmurzynska.com ?
With the same transparency effect that has.

I already did some small css customization on my website you can see http://www.pixhoster.info/f/2016-10/bb31a4772e74dfef8897d36337b323cc.png
But i would like the slider goes down of the header.

Ps: i use the header N° 3

Thanks lot 🙂
