Custom Footer Image (Brine)

Hello,

I'm trying to implement a custom footer image using the 'Custom CSS' section. Ideally I'd like to set an image for desktop and a different version for mobile. We're currently using the Brine template and trying the following code to no success:

#footer { background-image: url(“https://static1.squarespace.com/static/5908a95e1b10e3089ef71d4d/t/59133e9fb8a79bbbbc3be338/1494433439356/footer+image+imagenamehere.jpg”);
};

The website is https://bird-cranberry-57se.squarespace.com (password: mah). 

Any help would be much appreciated!
Cheers,

Andrés
