Make canvas transparent
<p>This is what my body looks like:</p>

<pre><code>body
{
    background-image:url('../images/bg.png');
    background-repeat:no-repeat;
    background-size:fixed 100vw;
    background-position:center;
}
</code></pre>

<p>The issue is, the canvas is white instead of being transparent. Is there a way to make it transparent so I can place the dna wave on top of a background?</p>
