When I adjust my config for Particles.js, the background color/image do not change from how it comes. I am not sure what I have done wrong. Here is my code:
HTML:
<script src="https://cdn.jsdelivr.net/particles.js/2.0.0/particles.min.js"></script>
<script src="js/app.js"></script>
<script>
particlesJS.load('particles-js', 'particles.json',
function(){
console.log('particles.json loaded...')
})
</script>
</div>
CSS:
head{
background-color: gray;
}
body{
background-color: gray;
}

I have tried various hex codes for background, none change it from red. I am not sure where it is getting the red from, but it is red... Background of website

Two things that I have noticed. You don't specify a js-particles div in your HTML. You have a closing div tag with no initial div tag. Before your <body>
tag, create a
<div id="particles-js"></div>
Then you can alter your CSS like in my snippet, as well as use the JSON in a particles function within a script tag instead of importing the JSON file
