Use Font Awesome icon as CSS content
Styling web elements with visually appealing icons can significantly enhance user experience and engagement. Leveraging Font Awesome, a vast library of scalable vector icons, allows developers to seamlessly integrate these icons as CSS content, offering a clean and efficient approach to web design. This method eliminates the need for additional image files, contributing to faster page load times and a smoother user experience. Let’s explore the power and flexibility of using Font Awesome icons as CSS content.
Setting Up Font Awesome
Before diving into implementation, ensure Font Awesome is integrated into your project. You can achieve this through a CDN link, downloading the Font Awesome files, or using a package manager like npm. The CDN method is often the easiest for quick integration, simply requiring you to add a link tag within the head of your HTML document. Once Font Awesome is set up, you’re ready to start styling.
Choosing the right integration method depends on your project’s specific needs. For instance, using npm offers more control and version management, while the CDN approach provides a quick and straightforward solution.
Basic Implementation with the content Property
The core of this technique lies in the CSS content property. This property, typically used with pseudo-elements like ::before and ::after, allows you to insert generated content into an element. To display a Font Awesome icon, you use the icon’s Unicode value within the content property. For example, to display the “user” icon, you would use the following CSS:
.element::before { font-family: "Font Awesome 5 Free"; content: "\f007"; }Remember to specify the correct Font Awesome font-family and the specific Unicode for your desired icon, which can be found on the Font Awesome website.
This simple yet powerful technique allows you to position icons precisely using CSS, providing granular control over alignment and spacing.
Styling and Positioning Icons
Once the icon is displayed, you can further style it using standard CSS properties. Adjust the font-size, color, and other properties to seamlessly integrate the icon with your design. Precise positioning is crucial for a polished look. Use properties like margin, padding, and position (along with top, left, right, and bottom) to achieve the desired placement.
For example, you can create a stylish button with a prepended icon:
button::before { font-family: "Font Awesome 5 Free"; content: "\f04b"; / Play icon / margin-right: 10px; }This positions the play icon neatly before the button text, enhancing visual appeal and user interaction.
Advanced Techniques and Best Practices
For more complex scenarios, you can leverage CSS variables to manage your icon Unicode values, improving code maintainability. Consider using a separate stylesheet specifically for your icon styles, keeping your project organized. Ensure proper accessibility by providing alternative text for screen readers, especially when icons convey essential information.
When using icons for interactive elements, be sure to consider user experience. Providing clear visual cues, like hover effects, can significantly improve usability and engagement. A well-placed tooltip can also enhance accessibility, providing context to users who might not immediately understand the icon’s meaning.
- Use CSS variables for easier management of icon codes.
- Prioritize accessibility by providing alternative text for screen readers.
- Choose your icon from Font Awesome.
- Find its Unicode value.
- Use the
contentproperty within your CSS to display the icon.
Featured Snippet: To use a Font Awesome icon as CSS content, use the content property with the icon’s Unicode value within a ::before or ::after pseudo-element. Ensure the correct Font Awesome font-family is declared.

Question & Answer :
I want to use a Font Awesome icon as CSS content, i.e.,
a:before { content: "<i class='fa...'>...</i>"; }
I know I cannot use HTML code in content, so is it only images left?
Update for FontAwesome 5 Thanks to Aurelien
You need to change the font-family to Font Awesome 5 Brands OR Font Awesome 5 Free, based on the type of icon you are trying to render. Also, do not forget to declare font-weight: 900;
a:before { font-family: "Font Awesome 5 Free"; content: "\f095"; display: inline-block; padding-right: 3px; vertical-align: middle; font-weight: 900; }
You can read the rest of the answer below to understand how it works and to know some workarounds for spacing between icon and the text.
FontAwesome 4 and below
That’s the wrong way to use it. Open the font awesome style sheet, go to the class of the font you want to use say fa-phone, copy the content property under that class with the entity, and use it like:
a:before { font-family: FontAwesome; content: "\f095"; }
Just make sure that if you are looking to target a specific a tag, then consider using a class instead to make it more specific like:
a.class_name:before { font-family: FontAwesome; content: "\f095"; }
Using the way above will stick the icon with the remaining text of yours, so if you want to have a bit of space between the two of them, make it display: inline-block; and use some padding-right:
a:before { font-family: FontAwesome; content: "\f095"; display: inline-block; padding-right: 3px; vertical-align: middle; }
Extending this answer further, since many might be having a requirement to change an icon on hover, so for that, we can write a separate selector and rules for :hover action:
a:hover:before { content: "\f099"; /* Code of the icon you want to change on hover */ }
Now in the above example, icon nudges because of the different size and you surely don’t want that, so you can set a fixed width on the base declaration like
a:before { /* Other properties here, look in the above code snippets */ width: 12px; /* add some desired width here to prevent nudge */ }
