You can write your own function.

 

var docStyle = getComputedStyle(document.documentElement);

function getProp(value) {
  return docStyle.getPropertyValue(value);
}

TweenMax.to(".foo", 1, {
  color: getProp("--red")
});

TweenMax.to(".bar", 1, {
  color: getProp("--some-other-value")
});

How would I go about animating the CSS variable itself? I have an inline variable on the parent as --color: RRR, GGG, BBB and this is used in multiple different color gradients on children as rgba(var(--color), 0.6) etc. I'd like to animate the values in the inline parent definition so the changes naturally propagate into the children instead of directly modifying them.

 

Nevermind  I found the answer here.
