I'm creating a website (may be seen at www.marcusvr.com.br/testes/saopaulo), and when trying to make it responsive everything worked well, except the menu: reduced to the hamburger button, its layout is almost invisible!

I know it wil follow the definitions of the desktop main menu, but isn't there a way to change its button's background properties to make it visible? The changing of the desktop template would make me loose all the website design...

If it isn't possible, it is a suggestion to be implemented in future updates.

Thanks in advance,

Marcus
