Mobile menu background

Hey there!

My current mobile menu background is just pure grey and I would like to put an image to it:

And preferably the navigation at the lower left corner of the image, How should I do this?

Add to Home > Design > Custom CSS

@media screen and (max-width:768px) {
div#overlayNav {
    background-image: url(https://beaverhero.com/wp-content/uploads/2019/06/trees-3464777_640-min.jpg);
    background-size: cover;
    background-repeat: no-repeat;
}
}
