Change search icon to box and move central, Impulse theme. Desktop only.

Hi all. 

I am hoping to move some elements around on my header, shifting my logo to the left and making the search icon a large search box in the centre of the header (as per below). I am using Impulse theme and am hoping to make changes on desktop only, leaving mobile as it currently is. 

My site is https://carolinegardner.com/ 

Any help with this would be gratefully received.

@davidfoster1983  this will need header code to be edited, result as per your requirement can be achieved. Only thing is that it will change on mobile view as well, but if you can accept me as collaborator then I can do it.
