How to change the drop down of he hamburger menu transparent

hi there,

i would like to make the drop down of the hamburger menu transparent,

and clue in css?

thanks in advance.

Hello there,

If could catch your point correctly, you would add the below custom CSS code through Appearance > Customize > Additional CSS:

#mainnav-mobi {
  background-color: transparent;  


hi Kharis,

thanks for your hint,

end up using

#mainnav-mobi {
background-color: rgba(0,0,0,0.5);

and it works too!
