Set position of image relative to other object-CodePudding

I'm having trouble to position a small image with it's center on the upper right corner of another box element. It should look something like that:

However I couldn't find a solution how to position it correctly outside of the container. The closest I could get is with:

<img src="cert.svg" style="position: absolute; height: 100px; top: 5vh; left: 30vw;">

But that's only a very rough solution, as it can break for example on different zoom factors and when resizing the browser window. Any ideas howto achieve this are appreciated!

Full code:

<!DOCTYPE html>
<html>

<style>
  .codebox {    
    width: 30vw;
    padding: 15px;
    font-family: Courier, sans-serif;
    color: #fff;
    background-color: #111927;
  }

  .codetitle {
    width: 30vw;
    padding: 5px 20px 5px 10px;
    font-family: Roboto, sans-serif;
    background-color: coral;
  }
</style>

<body>
<p>Lorem ipsum</p>
    <img src="image.png" style="position: absolute; height: 100px; top: 5vh; left: 30vw;">
    <div >Sourcecode:</div>
    <div  style="font-family: Courier, monospace;">
        <p><code>
            This is some source code.
        </code></p>
    </div>
</body>
</html>

To achieve the above result, you could add position: relative; to codebox's style. Then, place the image inside the codebox and place it at top: 0; right: 0;.

If you need it to go more up, you could use a negative value for top attribute.

    background-color: #111927;
  }

  .codetitle {
    width: 30vw;
    padding: 5px 20px 5px 10px;

    background-color: coral;
