The flipper component is most often used to page through blocks of content or collections of ui elements. As flippers are often a supplemental form of navigation, the flippers are hidden by default to avoid duplicate keyboard interaction. Passing an attribute of `aria-hidden="false"` will expose the flippers to assistive technology.

## Setup

### Basic Setup

```ts
import {
    provideFASTDesignSystem,
    fastFlipper
} from "@microsoft/fast-components";

provideFASTDesignSystem()
    .register(
        fastFlipper()
    );
```

### Customizing Icons

```ts
import {
    provideFASTDesignSystem,
    fastFlipper
} from "@microsoft/fast-components";

provideFASTDesignSystem()
    .register(
        fastFlipper({
            next: `...your next icon...`,
            previous: `...your previous icon...`,
        })
    );
```

## Usage

### Previous

```html live
<fast-flipper direction="previous"></fast-flipper>
```

### Next

```html live
<fast-flipper direction="next"></fast-flipper>
```

## Create your own design

```ts
import {
    Flipper,
    FlipperOptions,
    flipperTemplate as template,
} from "@microsoft/fast-foundation";
import { flipperStyles as styles } from "./my-flipper.styles";

export const myFlipper = Flipper.compose<FlipperOptions>({
    baseName: "flipper",
    template,
    styles,
    next: `...default next icon...`,
    previous: `...default previous icon...`,
});
```
