Hi, I'm trying to add an animated background to my website. The background is interactive, the particles follow the mouse. I've gotten the code from CodePen however when I put it into the html iframe, nothing happens. I can add anything else from codepen on my site but for some reason the interactive backgrounds don't work. Any suggestions?
P.S I'm not an expert with coding, I'm just creating a site for a friend who isn't tech-savy.
