Make P5 Sketch Section Background

CharlesDesign

I'm configuring a bootstrap theme and I'd like to set a p5 sketch as the background to one of the section.

Unfortunately everytime I add a div or a canvas to the section it displaces other components.

My question is; how can I insert a sketch as the background to this section without disturbing anything else?

Thanks for your help!

<section class="resume-section p-3 p-lg-5 d-flex d-column" id="about">
    <div id="container"></div>
    <div class="my-auto">
        <h1 class="mb-0">Charles
                <span class="text-primary">Fried</span>
              </h1>
        <div class="subheading mb-5">Give a description
            <a href="mailto:name@email.com">name@email.com</a>
        </div>
        <p class="mb-5">Blahhhhhhh</p>
        <ul class="list-inline list-social-icons mb-0">
            <li class="list-inline-item">
                <a href="#">
                    <span class="fa-stack fa-lg">
                      <i class="fa fa-circle fa-stack-2x"></i>

                  </a>
            </li>
            <li class="list-inline-item">
                <a href="#">
                    <span class="fa-stack fa-lg">

            <li class="list-inline-item">
                <a href="#">

                      <i class="fa fa-linkedin fa-stack-1x fa-inverse"></i>
                    </span>
                  </a>
            </li>
            <li class="list-inline-item">
                <a href="#">
                    <span class="fa-stack fa-lg">
                      <i class="fa fa-circle fa-stack-2x"></i>
                      <i class="fa fa-github fa-stack-1x fa-inverse"></i>
                    </span>
                  </a>
            </li>
        </ul>
    </div>
</section>

Here's the P5 code:

function setup() {

    var clientHeight = document.getElementById('about').clientHeight;
    var clientWidth = document.getElementById('about').clientWidth;

    var cnv = createCanvas(clientHeight, clientWidth);
    cnv.parent("container");
    background(0);
}

Use CSS. Not tested; but something like this (probably with some adjustment) should work:

#about {
  position: relative;
}

#container {
  position: absolute;
  top: 0;
  left: 0;
}

/* you may need to give .my-auto a z-index to put it on top of #container */
.my-auto {
  z-index: 100;
}
