Can I assign a CSS variable to another?

Can I assign one globally defined CSS variable to another locally define variable?

For example, the variable --dark has been globally defined as black.

Then, I want to be able to do:

:root {
    --background-color: --dark
}

.light {
    --background-color: white
}

div {
   background-color: --background-color
}

So that by default, my div will have a black background. And when the class light is added to it, it will have a white background.

I need the 'default' --dark variable here because it is a theme variable.

You should assign as var(--dark)

:root {
    --dark : black;
    --background-color: var(--dark);
}

.light {
    --background-color: white;
}

div {
  height: 100px;
  width: 100px;
  background-color: var(--background-color);
}
<div class="light"></div>
<div></div>
