Stacking Icons

You can stack our icons easily with the support styling bundled with Font Awesome.

We’ll cover the basics of aligning stacked icons alongside single icons, changing default font size, changing the default font size with stacking, and simple CSS customizations.

To stack multiple icons, use the fa-stack class on the parent HTML element of the 2 icons you want to stack. Then add the fa-stack-1x class for the regularly sized icon and add the fa-stack-2x class for the larger icon. fa-inverse can be added to the icon with the fa-stack-1x to help with a knock-out looking effect. You can even throw larger icon classes on the parent to get further control of sizing.

<span class="fa-stack fa-2x">
  <i class="fa-solid fa-square fa-stack-2x"></i>
  <i class="fab fa-twitter fa-stack-1x fa-inverse"></i>
</span>
<span class="fa-stack fa-2x">
  <i class="fa-solid fa-circle fa-stack-2x"></i>
  <i class="fa-solid fa-flag fa-stack-1x fa-inverse"></i>
</span>
<span class="fa-stack fa-2x">
  <i class="fa-solid fa-camera fa-stack-1x"></i>
  <i class="fa-solid fa-ban fa-stack-2x" style="color:Tomato"></i>
</span>
<span class="fa-stack fa-2x">
  <i class="fa-solid fa-square fa-stack-2x"></i>
  <i class="fa-solid fa-terminal fa-stack-1x fa-inverse"></i>
</span>
<span class="fa-stack fa-4x">
  <i class="fa-solid fa-square fa-stack-2x"></i>
  <i class="fa-solid fa-terminal fa-stack-1x fa-inverse"></i>
</span>

Aligning Stacked and Regular Icons

You can use stacked icons right alongside single icons. Since stacked icons are styled by our framework’s included CSS to be twice the size of single icons, you’ll need to either size down the stacked icon or size up the single icons.

<i class="fa-regular fa-circle fa-2x"></i>
<span class="fa-stack" style="vertical-align: top;">
  <i class="fa-regular fa-circle fa-stack-2x"></i>
  <i class="fa-solid fa-flag fa-stack-1x"></i>
</span>
<span class="fa-stack" style="vertical-align: top;">
  <i class="fa-solid fa-circle fa-stack-2x"></i>
  <i class="fa-solid fa-flag fa-stack-1x fa-inverse"></i>
</span>
<i class="fa-regular fa-circle fa-2x"></i>

Changing the Default Font Size with Stacking

When you stack icons but change the font-size, you’ll need to make some adjustments to your CSS to keep the icons aligned.

<style>
  .fa-stack.small {
    font-size: 0.5em;
  }
  i {
    vertical-align: middle;
  }
</style>
<i class="fa-regular fa-circle"></i>
<span class="fa-stack small">
  <i class="fa-regular fa-circle fa-stack-2x"></i>
  <i class="fa-solid fa-flag fa-stack-1x"></i>
</span>
<span class="fa-stack small">
  <i class="fa-solid fa-circle fa-stack-2x"></i>
  <i class="fa-solid fa-flag fa-stack-1x fa-inverse"></i>
</span>
<i class="fa-regular fa-circle"></i>
