Heading Menu Font Issue ( Shopify Dawn Theme )

[dreamtechzone_5]

Hello Everyone!

I have changed the font of the heading menu. It is perfect in desktop mode, but the heading menu font has not changed in mobile mode. I want to keep the same font in all formats, like desktop, mobile, laptop, and tablet. I only want to change the heading menu font and not change anything else. I want to keep the Highway Gothic font as a heading menu. Please help me. Thank you. I have used this code.
