google chrome - CSS :focus not working

Question

I tried using :focus CSS pseudo-class in my project. I want to change the color of the element where I click on it. Now when I click my element change color only where it is active and after mouse up it return to old color. After second click I want it back to old color. I'm using Chrome.

.row {
  display: inline-block;
  border: 1px solid grey;
  height: 200px;
  width: 200px;
  line-height: 1em;
  background: grey;
  margin: 5px;
  opacity: 0.1;
}
.row:active,
.row:focus {
  background: orange;
}

<div id="main" class="container">
  <div class="row" id="row0">
  </div>
</div>

If you want a real focus state to a div element, you can add a tabindex attribute to it.

.row {
display:inline-block;
  border:1px solid grey;  
  height:200px;
  width: 200px;
  line-height:1em;
  background: grey;
  margin: 5px;
   opacity: 0.1;
}

.row:active, .row:focus { background: orange; }
 

<div id="main" class="container">
<div class="row" tabindex="1" id="row0">
</div>
</div>
