Font Awesome icons can be customized even further using your own CSS. We've even added CSS Custom Properties to our style toolkit options.

Using Custom Properties in a Project

CSS custom properties are still a pretty new thing for most folks. Here are some ways you can define them within your project…

Setting Properties with CSS :root

You can define custom properties at CSS :root pseudo-class level. This will make any icons that use a styling toolkit's feature inherit the properties by default.

  <!-- by default, everything will be in V6's regular style and in the holiday spirit -->
  <style>
    :root {
      --fa-style-family: "Font Awesome 6 Pro";
      --fa-style: 400;
      --fa-border-color: red;
      --fa-primary-color: green;
      --fa-secondary-color: red;
    }
  </style>

Setting Properties with Project-Based CSS Rules

You can also set custom properties inside of your project's CSS, in the <head> of a page or in a separate stylesheet. These properties will be scoped to just elements that match the selector of the rule you've included them in.

  <style>
    /* setting a decorative icon dropcap before a block of text */
    .ye-olde-icon-dropcap {
      --fa-border-color: WhiteSmoke;
      --fa-border-padding: 2em;
      --fa-border-radius: 0.25em;
      --fa-pull-margin: 2em;

      font-size: 8em;
    }
    
    /* playing DJ with fa-record-vinyl */
    .track-quick-spin {
      --fa-spin-duration: 0.25s;
      --fa-spin-iteration-count: 1;
      --fa-spin-timing: ease-out;
    }

    .track-vocals {
      --fa-spin-duration: 10s;
      --fa-spin-timing: ease-in-out;
      --fa-spin-iteration-count: 2;
    }

    .track-dope-hook {
      --fa-spin-duration: 10s;
      --fa-spin-iteration-count: 10;
    }

    /* Mo' Malfoy! Mo' Malfoy! Mo' Malfoy! */
    .theme-slytherin {
      --fa-primary-color: darkgreen;
      --fa-secondary-color: silver;
    }
  </style>

Setting Properties with Inline Styles

Many of the examples in these docs define CSS custom properties using inline styling by adding a style attribute to an element. This is best for one-offs or very custom colored/styled duotone icons that you won't need to change at a system level.

  <!-- rotating an icon -->
  <i class="fa-solid fa-bomb fa-rotate-by" style="--fa-rotate-angle: 45deg;"></i>
  
   <!-- using inline styles to define duotone icon custom properties -->
  <i class="fa-duotone  fa-crow" style="--fa-primary-color: dodgerblue; --fa-secondary-color: gold;"></i>

Be careful of specificity and cascade!

CSS Custom properties that are redefined will trump each other. Defining a property in :root {} and then defining the same property in a rule or inline will result in the :root style being overridden.

Add Your Own Custom Styling with CSS

You can also add your own custom styling to Font Awesome icons by adding your own CSS rules in your project's code. Everything you can normally control with CSS is up for grabs - from color to display to alignment. We recommend targeting icons in your CSS in couple of different ways.

Styling Case	Recommended Selector
Custom styling all icons	Add a consistent custom class to all icons (e.g. .icon, .[projectprefix]-icon, or .fa-icon) You can also use style-classes for the in-use icon styles .fa-solid { ... } .fa-regular { ... } .fa-light { ... } .fa-thin { ... } .fa-duotone { ... } .fa-brands { ... }
Custom styling a specific icon	Use the individual icon name, prefixed with .fa- .fa-user { ... } .fa-font-awesome { ... }

Here's a quick example of using those selectors to add custom color to Font Awesome icons:

  <head>
    <!-- reference your copy Font Awesome here (from our CDN or by hosting yourself) -->
    <link href="/your-path-to-fontawesome/css/fontawesome.css" rel="stylesheet">
    <link href="/your-path-to-fontawesome/css/brands.css" rel="stylesheet">
    <link href="/your-path-to-fontawesome/css/solid.css" rel="stylesheet">
    <style>
      /* custom styling for all icons */
      .live-example .fa-solid,
      .live-example .fa-brands {
        background-color: papayawhip;
        border-radius: .2em;
        padding: .3em;
      }

      /* custom styling for specific icons */
      .fa-fish {
        color: salmon;
      }

      .fa-frog {
        color: green;
      }

      .fa-user-ninja.vanished {
        opacity: 0.2;
      }

      .fa-facebook {
        color: rgb(59, 91, 152);
      }
    </style>
  </head>
  <body>
    <i class="fa-solid fa-fish"></i>
    <i class="fa-solid fa-frog"></i>
    <i class="fa-solid fa-user-ninja vanished"></i>
    <i class="fa-brands fa-facebook"></i>
  </body>

Writing Custom CSS with our SVG + JS framework

When using our SVG framework, remember that Font Awesome-based <i> DOM elements are replaced with new <svg> elements by default. Be sure that your CSS rules target the right elements.
