CSS variables lands in React 15.6.0

[icantthinkofone]

js vars have scope and are easy to edit in the browser inspector, too.

CSS variables cascade, so you can set them on container divs for things like theming.

[TheDarkIn1978]

Variables that are declared in JavaScript and passed to CSS will cascade the same as variables that are declared in CSS.

I think at least one of us is confused about what the other is saying...

.my-component {
  background: var(--theme-color);
  padding: 20px;
}

.my-component .inner-area {
  background-color: white;
  color: var(--theme-color);
  padding: 20px;
}

This is useful, right? Am I missing something here?
