How to disable submit button & links on-click in pure CSS?

One idea is to have a layer that come on the top of the element after the first click to avoid the second one.

Here is a basic idea where I will consider a duration of 1s between two clicks that you can decrease. Try to click the button/link and you will notice that you can click again only after 1s.

I am adding a small overlay to better see the trick

.button {
  position:relative;
  display:inline-block;
}
.button span{
  position:absolute;
  top:0;
  left:0;
  right:0;
  bottom:100%;
  z-index:-1;
  animation:overlay 1s 0s; /* Update this value to adjust the duration */
  transition:0s 2s; /* not this one! this one need to be at least equal to the above or bigger*/
}


.button *:active + span {
  animation:none;
  bottom:0;
  transition:0s 0s;
}

@keyframes overlay {
  0%,100% {
    z-index:999;
    background:rgba(255,0,0,0.2); /* To illustrate */
  }
}
<div class="button">
  <button>Click me</button>
  <span></span>
</div>

<div class="button">
  <a href="#" onclick="console.log('clicked !')">Click me</a>
  <span></span>
</div>
