Less
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!
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.

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.
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.
If you wanted to use more styles, add more style imports:
Using Duotone Icons
If a project uses Duotone icons, you’ll need to @import
two separate files.
Using a Downloaded Kit
Starting with version 6.4, you can now download a Kit to compile and host yourself just like you do with Font Awesome! To download your Kit, make sure the Kit’s version in Settings is set to “Latest 6.x” or if you selected a specific version, it needs to be at least 6.4. Then from the Set Up tab in your Kit, you’ll see the options for downloading. Your kit download will contain all of the Less files noted above.
Custom Icons in Downloaded Kits
If you have custom icons in your Kit, they will be included as an additional files in your Kit download.
Path to the files | What the files do |
---|---|
/webfonts/custom-icons.woff /webfonts/custom-icons.ttf | Custom icon font in WOFF2 and TTF formats |
/less/custom-icons.less | Less Preprocessor partial that handles the display of custom icons using Web Fonts |
Here’s a simple example that follows the compile steps above along with custom icons:
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:
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.
Style Mixins
To use the style mixins, you’ll want to:
- Choose the right mixin for your desired style style.
- 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 |
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 |
fa-family-sharp-duotone() | Pro only | Sharp Duotone 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:
- Get the core set up styling of icons by adding
.fa-icon;
- Use
.fa-solid;
to include the styling to render the icon in the Solid style (similar syntax for other styles) - Use
.fa-classic;
or.fa-sharp;
to include the styling to render the icon in a specific family (Classic is set by default) - 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
Included Mixins
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 |
.fa-icon-solid() .fa-icon-regular() .fa-icon-light() .fa-icon-thin() .fa-icon-duotone() .fa-icon-brands() | Mixins that contain all of the base style set up for an icon along with a specific style to render the icon in |
.fa-family-sharp-duotone() .fa-family-sharp() .fa-family-classic() .fa-family-sharp-duotone() | Mixins that, when combined with .fa-icon- style mixins, define the family of styles to be used. |
.fa-size() | A mixin that calculates font size and vertical alignment for the relative sizing scale |
.fa-sr-only() | A mixin that visually hides an element containing a text-equivalent for an icon while keeping it accessible to assistive technologies |
.fa-sr-only-focusable() | A mixin that is used alongside .fa-sr-only() to show the element again when it’s focused (e.g. by a keyboard-only user) |
