Usage

Ionicons is a completely open-source icon set with 1,300 icons crafted for web, iOS, Android, and desktop apps. Ionicons was made for Ionic Framework, a cross-platform hybrid and Progressive Web App framework.

Using the Web Component

The Ionicons Web Component is an easy and performant way to use Ionicons in your app. The component will dynamically load an SVG for each icon, so your app is only requesting the icons that you need.

Also note that only visible icons are loaded, and icons which are "below the fold" and hidden from the user's view do not make fetch requests for the svg resource.

Installation

If you're using Ionic Framework, Ionicons is packaged by default, so no installation is necessary. Want to use Ionicons without Ionic Framework? Place the following <script> near the end of your page, right before the closing </body> tag, to enable them.

<script type="module" src="https://unpkg.com/ionicons@7.1.0/dist/ionicons/ionicons.esm.js"></script>
<script nomodule src="https://unpkg.com/ionicons@7.1.0/dist/ionicons/ionicons.js"></script>

Basic usage

To use a built-in icon from the Ionicons package, populate the name attribute on the ion-icon component:

<ion-icon name="heart"></ion-icon>

Custom icons

To use a custom SVG, provide its url in the src attribute to request the external SVG file. The src attribute works the same as <img src="..."> in that the url must be accessible from the webpage that's making a request for the image. Additionally, the external file can only be a valid svg and does not allow scripts or events within the svg element.

<ion-icon src="/path/to/external/file.svg"></ion-icon>

Variants

Each app icon in Ionicons has a filled, outline and sharp variant. These different variants are provided to make your app feel native to a variety of platforms. The filled variant uses the default name without a suffix. Note: Logo icons do not have outline or sharp variants.

<ion-icon name="heart"></ion-icon> <!--filled-->
<ion-icon name="heart-outline"></ion-icon> <!--outline-->
<ion-icon name="heart-sharp"></ion-icon> <!--sharp-->

Platform specificity

When using icons in Ionic Framework you can specify different icons per platform. Use the md and ios attributes and provide the platform specific icon/variant name.

<ion-icon ios="heart-outline" md="heart-sharp"></ion-icon>

Size

To specify the icon size, you can use the size attribute for our pre-defined font sizes.

<ion-icon size="small"></ion-icon>
<ion-icon size="large"></ion-icon>

Or you can set a specific size by applying the font-size CSS property on the ion-icon component. It's recommended to use pixel sizes that are a multiple of 8 (8, 16, 32, 64, etc.)

ion-icon {
  font-size: 64px;
}

Color

Specify the icon color by applying the color CSS property on the ion-icon component.

ion-icon {
  color: blue;
}

Stroke width

When using an outline icon variant it is possible to adjust the stroke width, for improved visual balance relative to the icon's size or relative to the width of adjacent text. You can set a specific size by applying the --ionicon-stroke-width CSS custom property to the ion-icon component. The default value is 32px.

<ion-icon name="heart-outline"></ion-icon>

ion-icon {
  --ionicon-stroke-width: 16px;
}

Accessibility

Icons that are purely decorative content should have aria-hidden="true". This will not visually hide the icon, but it will hide the element from assistive technology.

<ion-icon name="heart" aria-hidden="true"></ion-icon>

If the icon is interactive, it should have alternate text defined by adding anaria-label.

<ion-icon name="heart" aria-label="Favorite"></ion-icon>

Alternatively, if the icon is inside of another element that it is describing, that element should have the aria-label added to it, and the icon should be hidden usingaria-hidden.

<ion-button aria-label="Favorite">
  <ion-icon name="heart" aria-hidden="true"></ion-icon>
</ion-button>
