Hello,
Thank you very much for replying, but that just changed the height of the header image. Even with that new height after adding that CSS, when you initially scroll down, the image can be seen to change size in the background and the scrolling is not smooth.
Interestingly you don’t get the same problem if you resize a desktop browser window to be narrow like the iPhone, so I’m not sure what’s going on.
See for yourself if you have a phone / tablet

Any help much appreciated.
