How to put a div above animated body without covering body

I have a website I'm working on to get a grasp on how to build websites using HTML, CSS, and JS. I'm running into an error where when I put a div above a background animation on the body, the background animation doesn't pass over the div. I don't know how to fix this, and none of my Internet searches seem to solve this issue.

Here is the CodePen for the program: https://codepen.io/ckneeland/pen/Exyjygx

The HTML file is like so:

<!DOCTYPE html>
<html lang="en" >
<head>

  <meta charset="UTF-8">
  <title>Data</title>
  <link rel="stylesheet" href="./style.css">
</head>
<body>
  <div class="wrapper fade-in" id="particles-js">
    <table class="center-table">
      <tr>
        <td><img class="resize" src="Images/Facebook.png" alt="Facebook"></td>
        <td><img class="resize" src="Images/Instagram.png" alt="Instagram"></td>
        <td><img class="resize" src="Images/Snapchat.png" alt="Snapchat"></td>
        <td><img class="resize" src="Images/Twitter.png" alt="Twitter"></td>
        <td><img class="resize" src="Images/YouTube.png" alt="YouTube"></td>
      </tr>
      <tr>
        <br>
        <br>
        <td><img class="resize" src="Images/TikTok.png" alt="TikTok"></td>
        <td><img class="resize2" src="Images/Google2.png" alt="Google"></td>
        <td><img class="resize" src="Images/Venmo2.png" alt="Venmo"></td>
        <td><img class="resize" src="Images/Reddit2.png" alt="Reddit"></td>
        <td><img class="resize" src="Images/LinkedIn.png" alt="LinkedIn"></td>
      </tr>
    </table>
  </div>
  <script src="http://cdn.jsdelivr.net/particles.js/2.0.0/particles.min.js"></script>
  <script src="./script.js"></script>
</body>
</html>

And the JS / CSS files are on the CodePen, but I don't think they're the issue here

The pictures won't show up since I didn't add them to the project here

Also, a small side note: How can I center this div object vertically? It is already centered horizontally.

    </div>

  <script src="./script.js"></script>
</body>
</html>

hope this is the result you looked for , basically I have added a div for the animated background separate from the wrapper fadein div , and fadein class determined as postion: fixed; than you can position it with left: xx; top:xx; right:xx; bottom:xx; properties

Use the developer tools to see where elements end. Then use absolute positioning along with an appropriate z-index to create an overlay.

In your example, as little as .center-table { position: absolute } could be what youre after.

As for your second question concenring vertical alignment, I suggest looking into layouting using flexbox.
