Place scalable vector icons anywhere in your content.

UIkit comes with its own SVG icon system and a comprehensive library, which comprises a growing number of elegant outline icons. This component injects SVGs into the site, so that they adopt color and can be styled with CSS.


Make sure to include the icon library script, for more details see the installation instructions.

To apply this component, add the uk-icon attribute to a <span> or <a> element. To display the actual icon, you need to append the icon: NAME parameter to the attribute. Et voilà, you have a vector icon that inherits color just like your text does.

<span uk-icon="icon: check"></span>

<a href="" uk-icon="icon: heart"></a>

If icon is the only option in the attribute value, you can also use uk-icon="NAME"

<span uk-icon="heart"></span>

  • <span class="uk-margin-small-right" uk-icon="check"></span>
    <a href="" uk-icon="heart"></a>


To view the list of all currently available icons. Please go to this documentation.


Add the ratio: 2 parameter to the uk-icon attribute to double its size – or any other number, depending on how big you want your icon to be.

<span uk-icon="icon: check; ratio: 2"></span>
Copy to clipboard
  • <span class="uk-margin-small-right" uk-icon="icon: check; ratio: 2"></span>
    <span uk-icon="icon: check; ratio: 3.5"></span>

To reset the default link styling to a more muted color when using an icon inside an anchor, add the .uk-icon-link class.

<a href="" class="uk-icon-link" uk-icon="heart"></a>
Copy to clipboard
  • <div>
      <a href="#" class="uk-icon-link uk-margin-small-right" uk-icon="copy"></a>
        class="uk-icon-link uk-margin-small-right"
      <a href="#" class="uk-icon-link" uk-icon="trash"></a>

Button modifier

Use the modifier .uk-icon-button class on an <a> element to create an icon button, which can be used for social icons.

<a href="" class="uk-icon-button" uk-icon="instagram"></a>
Copy to clipboard
  • <div>
        class="uk-icon-button uk-margin-small-right"
        uk-icon="ratio: 0.8; icon: instagram"
        class="uk-icon-button uk-margin-small-right"
        uk-icon="ratio: 0.8; icon: facebook"
      <a href="" class="uk-icon-button" uk-icon="ratio: 0.8; icon: youtube"></a>
