### Design Token CSS Custom Property dependency

<!-- AURO-GENERATED-CONTENT:START (REMOTE:url=https://raw.githubusercontent.com/AlaskaAirlines/WC-Generator/master/componentDocs/partials/development/designTokens.md) -->
The use of any Auro custom element has a dependency on the [Auro Design Tokens](https://auro.alaskaair.com/getting-started/developers/design-tokens).

<!-- AURO-GENERATED-CONTENT:END -->

### CSS Custom Property fallbacks

<!-- AURO-GENERATED-CONTENT:START (REMOTE:url=https://raw.githubusercontent.com/AlaskaAirlines/WC-Generator/master/componentDocs/partials/usage/cssFallbacks.md) -->
[CSS custom properties](https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties) are [not supported](https://auro.alaskaair.com/support/custom-properties) in older browsers. For this, fallback properties are pre-generated and included with the npm.

Any update to the Auro Design Tokens will be immediately reflected with browsers that support CSS custom properties, legacy browsers will require updated components with pre-generated fallback properties.

## Install bundled assets from CDN

<!-- AURO-GENERATED-CONTENT:START (REMOTE:url=https://raw.githubusercontent.com/AlaskaAirlines/WC-Generator/master/componentDocs/partials/usage/bundleInstallDescription.md) -->
In cases where the project is not able to process JS assets, there are pre-processed assets available for use. See -- `auro-carousel__bundled.js` for modern browsers. Legacy browsers such as IE11 are no longer supported.

We recommend you load these bundles using [differential serving](https://philipwalton.com/articles/deploying-es2015-code-in-production-today/) so that the browser only loads the bundle correctly. To accomplish this, the script tag for the modern bundle should have `type="module"` and the script tag.
