You could add a class to a DOM element using the classList property. See the MDN entry for classList: https://developer.mozilla.org/en-US/docs/Web/API/Element/classList

You could then remove the class using a setTimeout function.

So your animation function could look something like this:

function animations() {
  var elem = document.getElementById("animate");

  elem.classList.add('fade-in'); // Add .fade-in class

  setTimeout(function() {
    elem.classList.remove('fade-in'); // Remove .fade-in class
  }, 5000); // 5000ms
}
