I believe I may be experiencing an issue with the use of 'style.display' in JavaScript

I'm encountering a small issue. I need a button to reveal more content. Therefore, I require a way to hide this content initially and display it upon clicking, with the ability to reverse this action by hiding it again.

Despite my efforts, the content inside id=more always appears on the page.

What I want is for it to remain hidden initially.

This is what I've attempted:

<button onclick="myFunction()">More</button>
<div class="black" id="more">
    <p>I was supercool guys.... bla bla bla bla</p>
</div>
<script>
function myFunction() {
  var x = document.getElementById('more');
  if (x.style.display == "none") {
    x.style.display = "block";
  } else {
    x.style.display = "none";
  }
}
</script>

I also tried the following with no noticeable changes:

<button onclick="myFunction()">More</button>
<div class="black" id="more">
    <p>I was supercool guys.... bla bla bla bla</p>
</div>
<script>
function myFunction() {
  var x = document.getElementById('more');
  if (x.style.display == "block") {
    x.style.display = "none";
  } else {
    x.style.display = "block";
  }
}
</script>

What could I be overlooking?

My project involves HTML, JavaScript, and PHP.

Everything is running smoothly. Take a look at the code snippet below.

#more {
  display: none
}
<button onclick="myFunction()">More</button>
<div class="black" id="more">
  <p>I am awesome guys.... yada yada yada yada</p>
</div>
<script>
  function myFunction() {
    var x = document.getElementById('more');
    if (x.style.display !== "block") {
      x.style.display = "block";
    } else {
      x.style.display = "none";
    }
  }
</script>
