How to stack/overlap more than 2 icons in Font Awesome ?

I have managed to stack/overlap 2 icons like this.

<span class="fa-stack fa-lg">
  <i class="fa fa-square-o fa-stack-2x"></i>
  <i class="fa fa-twitter fa-stack-1x"></i>
</span>

http://jsfiddle.net/npLWz/ ref: http://fontawesome.io/examples/#stacked

but when i try to stack/overlap 3 or more icons like this.

<span class="fa-stack fa-3x">
  <i class="fa fa-square-o fa-stack-3x"></i>
  <i class="fa fa-square-o fa-stack-2x"></i>
  <i class="fa fa-square-o fa-stack-1x"></i>
</span>

Its getting messed up, any idea , how can i fix it ? and get 3 or more icons stacked/overlapped on each other.

Answer 1

I had a similar issue and solved using some custom CSS.

.icon-stack {
  position: relative;
  display: inline-block;
  width: 2em;
  height: 2em;
  line-height: 2em;
  vertical-align: middle;
}
.icon-stack-1x,
.icon-stack-2x,
.icon-stack-3x {
  position: absolute;
  left: 0;
  width: 100%;
  text-align: center;
}
.icon-stack-1x {
  line-height: inherit;
}
.icon-stack-2x {
  font-size: 1.5em;
}
.icon-stack-3x {
  font-size: 2em;
}

Markup is therefore:

<span class="icon-stack fa-3x">
   <i class="fa fa-{{whatever icon 3}} icon-stack-3x"></i>
   <i class="fa fa-{{whatever icon 2}} icon-stack-2x"></i>
   <i class="fa fa-{{whatever icon 1}} icon-stack-1x"></i>
</span>

I decided rather than override fa-stack I'd duplicate so I can still use the original CSS if required.

You can obviously play around with the font size, line height etc to suit your own requirements.

This feature is currently provided by fontawesome.

Answer 3

Finally, a new feature from Font-Awesome was released and now you can stack more than 2 icons:
