Uncovering Hidden Div Elements using Chrome Developer Tools

I have developed my own HTML editor, which you can access at this link: HTML Editor.

Below is the relevant source code:

const previewer = document.querySelector('iframe'),
  editor = document.querySelector('textarea'),
  // other variables and functions...

html,
body {
  height: 100%;
  padding: 0;
  margin: 0;
}

// CSS styles...


<header>
  <a href="" download="template.html" id="downloadLink" title="Download HTML document">Download</a>
  <!-- Other header elements -->
</header>

<main>
  <!-- Main content of the editor -->
</main>

<footer>
  <!-- Footer content -->
  <div id="cccTost"></div>
</footer>

After inspecting the page in Chrome Developer Tools, I found an unexpected div element at the end of the body:

<div id="cccTost"></div>

This added div is not part of my original source code. Can anyone help me understand why it's being inserted into the DOM and how to prevent it?

Answer №1

Thank you for posing this insightful question.

The 

<div id="cccTost"></div>
section is actually generated by the innovative Click Copy {Code} extension.

If one were to examine the source code of this plugin, specifically lines 8 through 12 in the script.js file, it becomes evident that the DOM element is created during the initialization phase of the extension.

init: function () {
    this.notificationDom();
    this.copyCode();
},
notificationDom: function () {
    let div = document.createElement('div');
    div.setAttribute("id", "cccTost");
    document.body.appendChild(div);
},
