Cognos Analytics

Does anyone know how I can adapt the following CSS so that it works with the Link Widget in dashboards. I can get basic stuff to work like colour, background etc but I dont see how to structure the hover effects etc so that cognos understands it. Any inights would be great.

<!-- HTML !-->
<button class="button-71" role="button">Button 71</button>

/* CSS */
.button-71 {
  background-color: #0078d0;
  border: 0;
  border-radius: 56px;
  color: #fff;
  cursor: pointer;
  display: inline-block;
  font-family: system-ui,-apple-system,system-ui,"Segoe UI",Roboto,Ubuntu,"Helvetica Neue",sans-serif;
  font-size: 18px;
  font-weight: 600;
  outline: 0;
  padding: 16px 21px;
  position: relative;
  text-align: center;
  text-decoration: none;
  transition: all .3s;
  user-select: none;
  -webkit-user-select: none;
  touch-action: manipulation;
}

.button-71:before {
  background-color: initial;
  background-image: linear-gradient(#fff 0, rgba(255, 255, 255, 0) 100%);
  border-radius: 125px;
  content: "";
  height: 50%;
  left: 4%;
  opacity: .5;
  position: absolute;
  top: 0;
  transition: all .3s;
  width: 92%;
}

.button-71:hover {
  box-shadow: rgba(255, 255, 255, .2) 0 3px 15px inset, rgba(0, 0, 0, .1) 0 3px 5px, rgba(0, 0, 0, .1) 0 10px 13px;
  transform: scale(1.05);
}

@media (min-width: 768px) {
  .button-71 {
    padding: 16px 48px;
  }
}
