Floating Widgets in the Header

Hi

I'm re-creating this site http://priyatourkow.com in GeneratePress and trying to work out the best way to do the header without it being a static image?

The development site is here : https://priya.swish-client.com/ and I have set up 2 widgets one to contain the text and the second for the image

Is this the best way to do this? and if so how do I get the 2nd widget with the image to float to the right of the header?

Thanks
