changing menu hamburger to PNG

Just have done that and It becomes perfect on the mobile ..made it 68px and it works perfectly there thank you).... but still appears small (65px) on other devices when at top of screen, but funnily it then becomes the correct size when you scroll down on those devices?

Did you change the value inside the "mobile" area? If you check my screenshot, you'll see there's a mobile icon next to the refresh icon.

Ahh silly me, yes have checked it now and everything is working perfectly.

Everything looks great with the site header, exactly as I wanted it.

Thank you so much for you help with this, perfect :-)

Awesome, glad I could help :)
