A full customization of particlejs
In this tutorial, we are going to Create awesome background effects with particles.js
Particles.js:
Particles.js is a lightweight, dependency-free, and responsive javascript plugin for particles background.
That means we can use it with bootstrap 4 or bootstrap 3 or without any UI framework just after writing some CSS and js. in this tutorial we are going to use bootstrap 4
Firstly we need particle.js plugin we can download it from Github or use any live CDN. In this tutorial, we will use downloadable particlejs.
Create index.html
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" integrity="sha384-JcKb8q3iqJ61gNV9KGb8thSsNjpSL0n8PARn9HuZOnIxN0hoP+VmmDGMN5t9UJ0Z" crossorigin="anonymous">
<link rel="stylesheet" href="css/style.css">
<!-- <script src="static/js/jquery.min.js"></script> -->
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<section class="banner" id="particles-js">
<div class="container-fluid ">
<div class="row">
<div class="col-12 p-0">
</div>
</div>
</div>
</section>
<script src="js/particles.js"></script>
Then we need some custom styling to form the background image
style.css
html{
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}
body{
font:normal 75% Arial, Helvetica, sans-serif;
}
canvas{
position: absolute;
top: 0px;
left: 0;
right: 0;
bottom: 0px;
height: 100%
}
.banner{
background: linear-gradient(rgba(0,0,0,.5), rgba(0,0,0,.5)),
url('https://picsum.photos/id/1025/1920/900');
background-position: top;
background-size: cover;
background-repeat: no-repeat;
overflow: hidden;
}
.banner .row{
min-height: 500px;
}
/* ---- particles.js container ---- */
#particles-js{
position: relative;
width: 100%;
height: 100%;
}
