Using Less as a CSS preprocessor in your project? No problemo, Font Awesome has a Less version if you'd prefer to import our styling into your workflow.

We’ll cover the basics of getting all the files you’ll need from the directory, adding Font Awesome to your compile, tools for referencing icons with ease, and more!

Before You Get Started

Make sure you:

Grab the Files

You'll find everything you need in the fontawesome6 directory of the Font Awesome download. Below is the list of files made specifically for Less. You can add them all to your project or pick just the ones you need.

Files What They Do
fontawesome.less Main Font Awesome compile
brands.less Brand icon styles
solid.less Solid icon styles
regular.less Regular icon styles
light.less Light icon styles
thin.less Thin icon styles
sharp-solid.less Sharp Solid icon styles
duotone.less Duotone icon styles
_variables.less Where variables are defined that are used throughout styling
_mixins.less Utilities used throughout styling/icon definitions
_core.less Base icon reference class syntax and definitions
_duotone-icons.less Duotone icon classes
_sizing.less icon sizing support styling
_fixed-width.less fixed-width icon support styling
_list.less icons in a list support styling
_bordered-pulled.less bordered + pulled icon support styling
_animated.less animated icon support styling
_rotated-flipped.less rotating icons support styling
_stacked.less stacking icons support styling
_icons.less All icon definitions
_screen-reader.less screen-reader specific and accessibility support styling

Adding Font Awesome to Your Compile

Copy the less folder into your project. Then copy the entire webfonts folder into your project, where your static files get served.

Open your project's less/variables.less and edit the @fa-font-path variable to point to where you placed the webfonts folder.

@fa-font-path: "../webfonts";

In your main Less compile file, import Font Awesome by adding the core styles file, @import "less/fontawesome.less". Then import one or more styles.

// importing core styling file
@import "./fontawesome/less/fontawesome.less";

@import "./fontawesome/less/solid.less";
@import "./fontawesome/less/brands.less";

If you wanted to use more styles, add more style imports:

// importing core styling file
@import "./fontawesome/less/fontawesome.less";

// our project needs Classic Solid, Brands, and Sharp Solid 
@import "./fontawesome/less/solid.less";
@import "./fontawesome/less/brands.less";
@import "./fontawesome/less/sharp-solid.less";

Using Duotone Icons

If a project uses Duotone icons, you'll need to @import two separate files.

// importing core styling file
@import "./fontawesome/less/fontawesome.less";

// our project needs Duotone - which requires both of the following files
@import "./fontawesome/less/duotone.less";
@import "./fontawesome/less/duotone-icons.less";

Ch-chigity Check Your Paths!

Make sure the font path and your webfonts directory are relative to where your compiled CSS will be located.

Autoprefixer is not included in v6!

For the sake of not being too prescriptive, we've removed Autoprefixer (opens new window) from our compile and build steps. If your project needs it, you'll need to add it yourself.

Adding Icons

Once you've added the imports above and have your compiled CSS that includes Font Awesome set up and referenced in your project, you can add icons to your project's HTML.

Here's an example of how to reference icons with your compiled and hosted CSS:

<head>
  <!--load your compiled CSS (including Font Awesome) -->
  <link href="/your-path-to-your-compiled-css-including-fontawesome/file.css" rel="stylesheet">
</head>
<body>
  <!-- This example uses <i> element with: 
  1. the `fa-solid` style class for solid style
  2. the `user` icon with the `fa-` prefix -->
  <i class="fa-solid fa-user"></i>

  <!-- Or you can use a <span> element, with classes applied in the same way -->
  <span class="fa-solid fa-user"></span>
</body>

Less Customizations at Your Command

Any changes to the Font Awesome Less variables (e.g. changing the fa- prefix or our sizing scales), will take effect in your project's compiled CSS.

Custom Less-based CSS Rules

If you want to use any of our Less mixins or utilities, you can leverage our CSS Pseudo-elements method of adding icons to your project to do. This method is also useful when changing the HTML on your project is not an option.

Using our .fa-icon- and .fa-family- style mixins, you can easily generate custom CSS Pseudo-element rules with CSS selectors specific to your project.

// Solid style of user
.user {
  .fa-icon-solid(@fa-var-user);
}

// Regular style of triangle-exclamation
.triangle-exclamation {
  .fa-icon-regular(@fa-var-triangle-exclamation);
}

// Light style of newspaper
.newspaper {
  .fa-icon-light(@fa-var-newspaper);
}

// Thin style of paintbrush-fine
.paintbrush-fine {
  .fa-icon-thin(@fa-var-paintbrush-fine);
}

// Duotone style of camera-retro
.camera-retro {
  .fa-icon-duotone(@fa-var-camera-retro);
}

// Twitter brand icon
.twitter {
  .fa-icon-brands(@fa-var-twitter);
}

// Sharp Solid style of trash
.trash {
  .fa-icon-solid(@fa-var-trash);
  .fa-family-sharp(); // define Sharp family
}

// Classic Solid style of trash
.trash {
  .fa-icon-solid(@fa-var-trash);
  .fa-family-classic(); // explicity setting Classic family (optional since this is Font Awesome's default)
}

Style Mixins

To use the style mixins, you'll want to:

  1. Choose the right mixin for your desired style style.
  2. Pass in the Less variable for the icon you want to display.
Style Mixin Availability What Style Renders
fa-icon-brands() Free Plan Brands
fa-icon-solid() Free Plan Solid
fa-icon-regular() Pro only [Regular
fa-icon-light() Pro only Light
fa-icon-thin() Pro only Thin
fa-icon-duotone() Pro only Duotone

Style Mixins Include Set Up Styles Too!

These style mixins also handle the basic rendering styles that we bundle in our toolkit to make sure icons display perfectly in their context and in browsers.

Family Mixins

If you're using our mixins to render an icon in a specific family, like our Sharp family of styles, you'll need to reference the right family mixin (e.g. .fa-family-sharp). Classic is our default family of styles, so there's no need to set it with a family mixin unless you're trying to explicitly set to override a previous family.

Family Mixin Availability What Style Renders
fa-family-classic() Free Plan Classic when used with other style mixins
fa-family-sharp() Pro only Sharp when used with other style mixins

A More Manual Custom CSS Approach

If you'd rather a more customizable approach when right your styling rules, we've made the utilties used in the style mixins available to get the same rendering results.

To write manual rules, you'll want to:

  1. Get the core set up styling of icons by adding .fa-icon;
  2. Use .fa-solid; to include the styling to render the icon in the Solid style (similar syntax for other styles)
  3. Use .fa-classic; or .fa-sharp; to include the styling to render the icon in a specific family (Classic is set by default)
  4. In a ::before pseudo-element rule, use icon variable names to make including an icon's Unicode values a little easier. This is similar in syntax to adding icons via pseudo-elements
// Solid style of user
.user {
  .fa-icon;
  .fa-solid;

  &::before {
    content: @fa-var-user;
  }
}

// Regular style of triangle-exclamation
.triangle-exclamation {
  .fa-icon;
  .fa-regular;

  &::before {
    content: @fa-var-triangle-exclamation;
  }
}

// Light style of newspaper
.newspaper {
  .fa-icon;
  .fa-light;

  &::before {
    content: @fa-var-newspaper;
  }
}

// Thin style of paintbrush-fine
.paintbrush-fine {
  .fa-icon;
  .fa-thin;

  &::before {
    content: @fa-var-paintbrush-fine;
  }
}

// Duotone style of camera-retro
.camera-retro {
  .fa-icon;
  .fa-duotone;

  &::before {
    content: @fa-var-camera-retro;
  }
}

// Twitter brand icon
.twitter {
  .fa-icon;
  .fa-brands;

  &::before {
    content: @fa-var-twitter;
  }
}

// Sharp Solid style of trash
.trash {
  .fa-icon;
  .fa-solid;
  .fa-sharp; // define Sharp family

  &::before {
    content: @fa-var-trash;
  }
}

// Classic Solid style of trash
.trash {
  .fa-icon;
  .fa-solid;
  .fa-classic; // explicity setting Classic family (optional since this is Font Awesome's default)

  &::before {
    content: @fa-var-trash;
  }
}

Included Mixins

Utilities What It Does
.fa-icon() A mixin that contains all of the base style set up for an icon (minus an icon's style and specific name/unicode) compile
