Help with particle.js not showing full screen

Hey all!

I have built a website for a company that I work for and I’ve added the particles.js effect to the landing page by adding the code to my home page header.

It displays and is responsive, however it does not fill the screen and it is driving me mad trying to fix it.

Any help would be massively appreciated!

Thanks -
