## Installation

```sh
npm install @material/mwc-icon
```

> NOTE: The Material Web Components are distributed as ES2017 JavaScript
> Modules, and use the Custom Elements API. They are compatible with all modern
> browsers including Chrome, Firefox, Safari, Edge, and IE11, but an additional
> tooling step is required to resolve *bare module specifiers*, as well as
> transpilation and polyfills for IE11. See
> [here](https://github.com/material-components/material-components-web-components#quick-start)
> for detailed instructions.

<mwc-icon>shopping_cart</mwc-icon>

<script type="module">
  import '@material/mwc-icon/mwc-icon.js';
</script>
```

```html
<a href="index.html">
  <mwc-icon>arrow_back</mwc-icon>
</a>
```

### Styled

<img src="https://raw.githubusercontent.com/material-components/material-components-web-components/6347c3e1b0264cc34cad24e4e52a23e2100a4926/packages/icon/images/accessible_forward.png" width="64px" height="64px">

```html
<style>
  .fancy {
    color: #03a9f4;
    --mdc-icon-size: 64px;
  }
</style>

<mwc-icon class="fancy">accessible_forward</mwc-icon>
```

## Fonts

Most users should include the following in their application HTML when using
icons:

```html
<link href="https://fonts.googleapis.com/css?family=Material+Icons&display=block" rel="stylesheet">
```

This loads the *Material Icons* font, which is required to render icons, and is
*not* loaded automatically. If you see plain text instead of an icon, then the
most likely cause is that the Material Icons font is not loaded.

To see all icons that are available in the Material Icons font, see
[Material Icons](https://material.io/resources/icons/).

For technical details about the Material Icons font, see the
[Material Icons Developer Guide](https://google.github.io/material-design-icons/).
