Gradient Button to background-color blinks on hover [duplicate]

Answer 1

I used only background for those. And used background:linear-gradient(#33afbd,#33afbd); instead of background-color:#33afbd;

a {
  text-transform: uppercase;
  border-radius: 3px;
  padding: 5px 20px;
  -ms-transition: all .4s ease-in-out;
  -moz-transition: all .4s ease-in-out;
  -o-transition: all .4s ease-in-out;
  -webkit-transition: all .4s ease-in-out;
  transition: all .4s ease-in-out;
  background: linear-gradient(to bottom, rgb(69, 225, 243), rgb(1, 201, 223));
  border: none;
  outline: none;
}

a:hover {
  background:linear-gradient(#33afbd,#33afbd);
}
