Hi Guys,

Just started my shopify store journey and only one issue I found and cannot solve.

When I highlight the menu, the background across the top turns white as per the screenshot below.

I found other similar posts but none of that code has worked.

Can someone please help me solve this issue? attached screenshot of what happens when I highlight the menu.

This doesnt happen when I highlight the logo.

Thanks
