.gradient-text {
  /* Fallback: Set a background color. */
  background-color: red;
  
  /* Create the gradient. */
  background-image: linear-gradient(45deg, #f3ec78, #af4261);
  
  /* Set the background size and repeat properties. */
  background-size: 100%;
  background-repeat: repeat;

  /* Use the text as a mask for the background. */
  /* This will show the gradient as a text color rather than element bg. */
  -webkit-background-clip: text;
  -webkit-text-fill-color: transparent; 
  -moz-background-clip: text;
  -moz-text-fill-color: transparent;
