CSS motion path onClick
You may also toggle a class
and use a transition
:
function myForwardFunction() {
document.getElementById("pathed").classList.add('to100');
}
function myBackFunction() {
document.getElementById("pathed").classList.toggle('to100');
}
section {
width: 244px;
height: 200px;
border: 2px dashed lightgrey;
}
body {
display: flex;
padding: 10px;
flex-wrap: wrap;
gap: 30px;
margin: 0;
height: 100vh;
justify-content: center;
align-items: center;

edit as suggested by @wizzwizz4 comment , you can use your js to set the onclick function on your button:
let btn = document.querySelector('#click');
let div = document.querySelector('#pathed');
btn.addEventListener("click", function() {
this.classList.toggle('to100');
div.classList.toggle('to100');
});
