Tips for creating a more seamless box transition within HTML

I've been searching for information on this topic, but I haven't been able to find a satisfactory answer.
I want to create a div that displays "Contact Us" and when clicked, smoothly reveals a layer with input fields.

I know I can use JavaScript to toggle between display:none and display:block, but how can I achieve a smooth transition?

Here's a basic example (the actual implementation will be more polished):

<div id="contact-us" onClick="showContactUs()">
<div id="contact-us-content" style="display: block;">
  Name - <input type="text" name="name">
  Email- <input type="text" name="email">
</div>
</div>

The accompanying JavaScript code is:

function showContactUs(){
   var contact = document.getElementById("contact-us-content");
   contact.style.display = "block";
}

If you have any tips or resources that could help me accomplish this task, please share them. I'm not very experienced with jQuery, but I am open to learning if it's a better solution.

If you're looking to achieve a smoother appearance without using display: block, one approach is to apply a transition effect on the opacity property. One way to implement this is by dynamically adding a class using JavaScript and handling the styling with CSS.

You can view an example of this in action here: https://jsfiddle.net/3wLrfk3d/

$(document).on('click', '#contact-us', show_contact_form)

function show_contact_form () {
    $('#contact-us-content').addClass('shown')
}

CSS:

#contact-us-content {
    opacity: 0;
    transition: opacity .5s ease;

    &.shown {
        opacity: 1;
    }
}

I utilized jQuery and Sass in my demonstration, but feel free to adapt it to vanilla JavaScript and CSS.

My usual approach is to transition the opacity, however, this results in the element still being present even when invisible, occupying space and blocking mouse events. To address this, I implement two classes: one for fading the element and another for completely hiding it once the fading process is complete:

$(function() {
var $box = $('.box');
$('.toggle').on('click', function() {
if (!($box).hasClass('visible')) {
    $box.addClass('transitioning');
setTimeout(function() {
      $box.addClass('visible');
      }, 1)
    } else {
    $box.removeClass('visible');
      setTimeout(function() {
    $box.removeClass('transitioning');
      }, 400)
    }
  })
})

body {
  font-family: Helvetica, Arial, sans-serif;
}

.box {
  background-color: #333;
  color: white;
  border: 5px solid white;
  padding: 50px 10px;
  box-shadow: 0 0 10px 0 rgba(0, 0, 0, .4);
  text-align: center;
  transition: opacity .4s ease-in-out;
  display: none;
  opacity: 0;
}

.transitioning {
  display: block;
}

.visible {
  opacity: 1;
}

.toggle {
  margin-bottom: 20px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="toggle">Toggle Box</button>
<div class="box">
  <h1>Hi there</h1>
</div>

Please note: This example is a quick demonstration and may behave strangely if the toggle button is clicked repeatedly. Handle at your discretion.
