Header not responsive

Hi There,

I’ve just tested the site using your theme – and notice that the customer header image isn’t responsive. Rather than resize on smaller screens / iPhones etc – it just gets cropped.

I’ve created a version of my logo as per your specifications – and uploaded it, but it’s not working.

Is there any way to fix this? I really want to use your theme – but need for it to function on mobile devices.

Thanks.
