It provides visual feedback to users, indicating that data is loading, by showing a shimmer animation on skeleton lines that match the shape of the content being loaded. ## Default Styling By default, the Skeleton Loader uses Qonto's branding: Default skeleton loader style ## Customization Options The Skeleton Loader can be customized using the following CSS variables: | CSS Variable | Description & Accepted Values | | -------------------------------------- | ------------------------------------------------------------------------------------------------------------------- | | `--qonto-embed-skeleton-border-radius` | Accepts any valid border-radius value (e.g., `4px`, `50%`, `8px`). Controls the border radius of the skeleton line. | There are some aspects of the loader skeleton that can't be customized. For example, it uses a shimmer animation and shows a neutral color (grayscale) that are designed to work well in most of the scenarios. ### Example This example shows a customized Skeleton Loader with different border radius: ```css theme={null} :root { --qonto-embed-skeleton-border-radius: 8px; } ``` The result is a skeleton loader with less rounded corners, as shown below: Customized skeleton loader style
