How to set particles-js to background? - javascript

I am trying to set up similar page as this, here with central element in front of animation that is running behind:
https://vincentgarreau.com/particles.js/#default
I set up something like this and it occupies its own space, separated from other content, not behind:
I would like my text appear in front of particles animation. Could you please help with this? I tried using "z-index" without success: <div style="z-index: -1"></div>
My full code is here, or pasted below with most important bits only.
I added this to my HTML:
<!-- particles.js container -->
<div id="particles-js"></div>
<!-- particles.js lib - https://github.com/VincentGarreau/particles.js -->
<script src="http://cdn.jsdelivr.net/particles.js/2.0.0/particles.min.js">
</script>
CSS:
body {
background-color: #789;
margin-left: 5px;
margin-right: 5px;
padding-top: 60px;
z-index: 900;
position:relative;

#particles-js {

document.body.appendChild(stats.domElement);
count_particles = document.querySelector(".js-count-particles");
update = function() {
stats.begin();
stats.end();
if (window.pJSDom[0].pJS.particles && window.pJSDom[0].pJS.particles.array) {
count_particles.innerText = window.pJSDom[0].pJS.particles.array.length;
}
requestAnimationFrame(update);
};
requestAnimationFrame(update);

The answer is by ZohirSalak CeNa:
setting your canvas to this position : absolute; width:100%;
height:100%; z-index:-1;
I would clarify for beginners:
In HTML the animated element is <div id="particles-js"></div>
This element should go to the background. Notice the value of id= element.
In CSS I simply added:
#particles-js {
position : absolute;
width:100%;
height:100%;
z-index:-1;
}
Notice after # the name that matches id= from HTML file (particles-js).
Now it looks like this:

How to fix content overlaps on transition between scenes and all pinned section also randomly loading on top of each other when using scrolltrigger?

When I create scroll animations using GSAP and Scrolltrigger with multiple scenes I face two issues. One is that when transitioning between two pinned sections the previous or next section tends to overlap. Another issue is suddenly from time to time (random) all the pinned sections overlap on top of each other making it look like the HTML is broken. Not sure why I face this issue any guidance will be helpful. Also any suggestions on how to modify the code to prevent repetition will help. Following is the code

Adding TSParticles params in React Particle

ApexCharts force 100% height

I've been struggling with this problem for a while, I need to have the 100% graphic at the height of your container.
To weights that I indicate to him that his height: '100%' still follows with spaces above and below, tabiem I gave false value to yaxis but still the problem persists.
Someone who can solve it would appreciate it.
var options = {
chart: {
type: 'line',
width: '100%',
height: '100%',
toolbar: {
show: false
},
},
grid: {
show: false,
padding: {
left: 0,
right: 0
}
},
tooltip: {
intersect: false,
x: {
show: false
},
marker: {
show: false
}
},
dataLabels: {
enabled: false
},
yaxis: {
show: false,
},
xaxis: {
tooltip: {
enabled: false
},
labels: {
show: false
},
axisBorder: {
show: false
}
},
series: [{
name: 'sales',
data: [30,40,35,50,49,60,70,91,125]
}]
}
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
#chart{
width: 500px;
height: 200px;
border: 1px solid #000;
}
<script src="https://cdn.jsdelivr.net/npm/apexcharts"></script>
<div id="chart"></div>
If you don't need x-axis, y-axis to be displayed, you can turn on the sparkline.enabled flag to remove all unnecessary spaces above and below chart area
chart: {
sparkline: {
enabled: true
}
}

Particle doesn't follow HTML order

I am trying to make Particle JS work as a background. As you can see on my website, the body as the attribute particles but, the particles are only after the content. It doesn't follow the order. Here is the config:

},
polygon: {

image: {
src: "img/github.svg",
width: 100,
height: 100
}
},
opacity: {

opacity_min: .1,

}
},

Thanks!
Try with that:
#particles-js {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
#particles-js > canvas {
position: fixed;
top: 0;
left: 0;
width: 100vw;
height: 100vh;
}
