Text does not display correctly to glow

[odiezbez]

I am trying to get my text to glow with the following code, not sure if I have done it correctly for css.

h1, h2, h3, h4, h5, h6 {
  margin-top: 0;
  margin-bottom: 0.5rem;
}

h1, h2, h3, h4, h5, h6,
.h1, .h2, .h3, .h4, .h5, .h6 {
  margin-bottom: 0.5rem;
  font-family: inherit;
  font-weight: 500;
  line-height: 1.2;
  color: inherit;
}

h1, .h1 {
  font-size: 2.5rem;
}

h2, .h2 {
  font-size: 2rem;
}

h3, .h3 {
  font-size: 1.75rem;
}

h4, .h4 {
  font-size: 1.5rem;
}

h5, .h5 {
  font-size: 1.25rem;
}

h6, .h6 {
  font-size: 1rem;
}

h1 .a{ /* use to make text glow in index.php */
    
 background-image: url("move.gif");
  background-size: cover;
  color: transparent;
  -moz-background-clip: text;
  -webkit-background-clip: text;
  text-transform: uppercase;
  font-size: 80px;
  margin: 5px 0;   
    }
h2 .b {  /* use to make text glow in index.php */
  background-image: url("move.gif");
