    ## Common Examples

    ### AI Variant

    Use the `ai` prop on any `Skeleton` component to apply blue gradient colors, signaling that AI-generated content is loading.

    <LiveCode showCode example="skeleton-ai" fullWidth screenshot>
      ```tsx lines expandable theme={null}
      import { Skeleton, Flex } from "@servicetitan/anvil2";

      function App() {
        return (
          <Flex direction="column" gap="5" style={{ width: "300px" }}>
            <Flex direction="row" gap="3" alignItems="center">
              <Skeleton.Circle ai diameter="2.5rem" />
              <Flex direction="column" gap="2" grow={1}>
                <Skeleton.Text ai variant="headline" />
                <Skeleton.Pill ai width="4rem" />
              </Flex>
            </Flex>
            <Skeleton.Text ai rows={3} />
            <Skeleton.Rectangle ai height="6rem" />
          </Flex>
        );
      }

      export default App;
      ```
    </LiveCode>

    ### With MobX

    This example shows how to use Skeleton with MobX, which is what ST app uses for data store. Refer to [How to use](/docs/web/components/skeleton/design#how-to-use) guide for the scope of Skeleton.

    ```tsx theme={null}
    import { observer } from "mobx-react-lite";
    import { useState, useEffect } from "react";

    const MobXExample = () => observer(() => {
      const { isLoading, data } = useStore(); // Assuming you have a MobX store

      return (
        {
          isLoading ? (
            <Card flexGrow="1" flexDirection="column" gap="2">
              <Skeleton.Circle diameter="3rem" />
              <Skeleton.Text variant="headline" />
              <Skeleton.Text rows="3"/>
            </Card>
          ) : (
            <Card flexGrow="1" flexDirection="column" gap="2">
              <Avatar name={data.name} size="large" />
              <Text variant="headline" el="p" size="small">{data.name}</Text>
              <Text>{data.description}</Text>
            </Card>
          )
        }
      )
    })
    ```

    ## Best Practices

    Do not use [`<Suspense>`](https://react.dev/reference/react/Suspense) as it requires the fetch to be using [`use()` hook](https://react.dev/reference/react/use).
