Mobile menu covered (2)

Hello,

Love simple banner, only unfortunately I do not know CSS and can therefore not make many adjustments to the banner.

I have the banner running well at the top of my header, however, it covers the header in the drop down menu on the mobile.

I would actually prefer it didnt show up at all in the drop down menu, as the menu is not really part of the page.

Also, wondering how I can change the font weight.

Thank you,
Erica
