Animated particles in page banner

Put some snazz in a banner using particles

Wanting to add some movement to our refreshed vihanti.com website, I found particles.js which I figured just might do the trick. But I didn’t want it over the whole site–just in the header banner. After tweaking the particles and downloading the json config, it was actually pretty simple!

The most important part was making sure that the parent element of the particles div was set to position: relative. That way, we can set the width and height of the particles to match the size of the hero banner.

import $ from 'jquery'
window.$ = $
window.jQuery = $

$(document).ready(() => {
   window.particlesJS.load('particles', 'assets/particles.json')
})
<!doctype html>
<html lang="en">
  <head>
    <script src="scripts/particles.js"></script>
  </head>
  <body>
    <section class="header hero has-text-centered is-relative">
      <div id="particles"></div>
      <div class="hero-head">
         {% include "partials/navigation.njk" %}
      </div>
      <div class="hero-body">
        {% block header %} {% endblock %}
      </div>
    </section>
  </body>
</html>
#particles {
  height: 100%;
  position: absolute;
  width: 100%;
}
