title: Is there any way to perform this animation with just one click if you want to repeat?
body: <p><a href="https://codepen.io/hugoC12/pen/gOrQyya" rel="nofollow noreferrer">CODEPEN</a></p>
  <pre><code>var btt = document.querySelector('.btt');
    btt.addEventListener('click', function(){
    this.classList.toggle('anime');
  });
  </code></pre>
  <p>How can I achieve this effect by clicking only once?</p>
