Hi Georgio!

The most sure-fire way to make transform-origin dead-center is to use 50% 50%.

But 180px 180px works just as well.

You get an error because of the space between .8s and ; in the line above (transition: transform .8s ;).

This passes:

* Complete the challenge by writing CSS below */
.star-bg{
  transition: fill 1s;
}

.star-bg:hover{
  fill: steelblue;
}

.star:hover{
  transform: rotate(180deg);
}

.star{
  transition: transform .8s;
  transform-origin: 180px 180px;

I hope that helps.

Stay safe and happy coding!
