I’m trying to make work a submition form using bootstrap + wp with a animated background using only css, the animation is working fine, but when i create the form into the same div container not working at all. I was Trying z-index css property, but can’t fix the problem, it look like the animation is overlay the form. I really don’t know how can i fix. I want to find the way the form work properly and with the animated background.

  overflow: hidden;
  position: absolute;
  top: 0;

  left: 0;
  right: 0;

.stars .stars-back {
  top: -50%;
  opacity: 0.5;
    radial-gradient(2px 2px at 20px 30px, #eee, rgba(0,0,0,0)),
    radial-gradient(2px 2px at 40px 70px, #fff, rgba(0,0,0,0)),
    radial-gradient(1px 1px at 90px 40px, #fff, rgba(0,0,0,0)),
