CSS pseudo class :focus after button click

Question

I was working with some basic CSS animation for button.The problem is the :focus pseudo class even works when we press tab on keyboard. So I want that :focus should only works when I click on the button i.e only when active.

Here is the code:

button {
  background: #c33;
  width: 150px;
  height: 30px;
  border: 0;
  color: #fff;
}

button:after {
  content: 'RENT ME';
  display: block;
}

button:active,
button:focus {
  background: green;
}

button:active:after,
button:focus:after {
  display: block;
  animation: shake 1s linear, revert 2s 1s;
  position: relative;
}

@keyframes shake {
  from {
    content: "O";
    font-family: FontAwesome;
    transform: rotate(0deg);
  }
  to {
    content: "O";
    font-family: FontAwesome;
    transform: rotate(360deg);
  }
}

@keyframes revert {
  0% {
    content: 'ADDED TO CART';
    left: -60px
  }
  50% {
    content: 'ADDED TO CART';
    left: 0px;
  }
  100% {
    content: 'ADDED TO CART';
    left: 0px;
  }
}

<button></button>
<button></button>

In the above code the button changes to green on press of tab which I want to avoid.Is there a pure CSS solution to it.

Answer 1

use tabIndex="-1" on button if you don't want the button to be focusable when pressing tab

<button tabIndex="-1"></button>
