Steps :-

For This Firstly create a .hidden class where the css display property is set to "none".

<style>
  .hidden{
    display:none;
  }
</style>

HTML

Then Using JavaScript we will toggle (add / remove) the hidden class from the element. So that results hiding and showing of the div/any other element.
Creating a JavaScript function to hide/show elements.

<script>
  function hideunhide(a){
    document.querySelector(a).classList.toggle('hidden');
  }
</script>

HTML

This function takes a parameter (queryselector) and select the element and add or remove hidden from the class list of the element. If hidden is present it will remove and vice-versa.That's the work of toggle.
