JavaScript
1

Hello Developers,
I am using Joomla and trying to set the background (Particle js).
I am getting a error as follows:
Uncaught TypeError: Cannot read property ‘getElementsByClassName’ of null
at window.particlesJS (particles1.js:1495)
at app.js:14
my website link is : http://www.testing.wi2wi.com/
I want to set particle js background for the product portfolio section.
Can anyone please help me?
Thank you.

There are no elements with the class name you’re trying to target is the most likely issue, that’s what the error is telling you.

You should really contact Joomla support about this. While we do offer technical help, we’re not a general support forum. We’re about helping people learn how to code.
