I have .svg that was generated by Illustrator that is being pulled in by css.
star.svg:
<?xml version="1.0" encoding="utf-8"?>

</svg>
css & html:
.star {
background: url(star.svg) no-repeat top center;
background-size: 100% 100%;
}
<div id="star" class="star"></div>
How do you change the opacity value inside the ".star_fill" class inside the svg using gsap?
