Can add a way to change Drawer container backgound color?

[chuoke]

For now drawer container background color is always white. And there is no way to change conveniently.
This is not very friendly for implementing a particular style of layout, such as this: https://codepen.io/chuoke/pen/BaqRpWE?editors=101.

css:

.q-drawer {
  background: transparent
}
