Particles.js as a background?
<p>I'm trying to use this example as a background but I can't seem to get it to work. </p>

<p>In order to get around this I'm forced to use a margin top of -1500px just to place my text over the top of it and it's causing major issues with responsiveness.</p>

<p>Does anyone have any idea on how I can use it strictly as a background?</p>

<p>The creator of the plugin has done it here on his website. </p>

<p>You can tell because when you inspect it, there is no "canvas" hovering over the top as there is on the CodePen example.</p>
