Here’s a sample of CSS Code to customize the display of the WordPress’ Gold Pricing Plugin:

.widget_block {
  padding: 0px !important;
  margin: 0px !important;
  border: 0px !important;
  }
  .r1 {
  width: 24.9%  !important;
  }
  .r2 {
  width: 24.9%  !important;
  }
  .r3 {
  width: 24.9%  !important;
  }
  .r4 {
  width: 24.9%  !important;
  }
  .metal-price {
  animation: blinker 10s linear infinite;
  color: red !important;
  }
  @keyframes blinker {
    50% {
      opacity: 0;
    }
  }
  .date {
  background-color: white !important;
  color: black !important;
  }
