So I want to add a function that when I click a div it moves, but when I click something else it moves back to its original position, I want to use gsap here too. I tried using an if else statement but I didn't know want to put in here(The part where there is two stars):

```js
let btnSide1 = document.querySelector('.button-side-one'),
        btnSide2 = document.querySelector('.button-side-two'),
        btnTop = document.querySelector('.button-top'),
        btnBig = document.querySelector('.button-big');
if (btnSide1 = **active**) {
  gsap.to(btnSide1, .5, { x: 3 })
} else {
  gsap.to(btnSide1, .5, { x: 0 }) 
}

```

here is the codepen link for this: <https://codepen.io/sowg/pen/GRvQxpN>
