by

Hello developers, In this post I shared code for Moving Particles with Javascript.

Often when you visit a website, these moving particles attract you. This can be done easily with particle JS.

Don’t forget to add particles.js CDN

  background-color: #b61924;
  background-image: url("");
  background-repeat: no-repeat;
  background-size: cover;
  background-position: 50% 50%;
}

#stats,
.count-particles{
  -webkit-user-select: none;
