# text.delta

How a number differs from the one it is compared with, beside it, like −74%: data-tone="good" or "bad" colours it by whether the change is an improvement; with no data-tone it stays hidden

Component: [`<Text>`](https://www.prongs.dev/docs/components/text.md) · Renders: `<span>` · Profile: [UI](https://www.prongs.dev/docs/intents/ui.md)

## Example

```tsx
<Text intent="text.delta">Pack my box with five dozen liquor jugs.</Text>
```

## Choosing between neighbours

Find the row that describes your element, and use the intent on the right.

| If it is for… | Use |
|---|---|
| How a number differs from the one it is compared with, beside it, like −74%: data-tone="good" or "bad" colours it by whether the change is an improvement; with no data-tone it stays hidden | `text.delta` (this page) |
| A status word | [`text.indicator`](https://www.prongs.dev/docs/intents/text/indicator.md) |

## Connections

Declared in the registry, both directions. Where an intent is used in your own code is something check and the gallery see; this site has no app code.

## For registry authors

**Starter intents.** These are the intents `prongs add` puts in your registry, shown in this site’s theme. Yours are your own `registry.ts`: rename, restyle and add to them, and see them with `prongs add gallery`.

What this intent is built from and its entry in `components/prongs/registry.ts`. You only need this to change how it looks or to add an intent like it.

How text.delta resolves, and its definition

Each layer adds to the one before it; a later class wins over an earlier one that sets the same thing.

- [`typography.mono`](https://www.prongs.dev/docs/intents/ui.md#typography-mono) — Monospaced type

  ```
  font-mono text-sm
  ```

- `text.delta` (this page) — How a number differs from the one it is compared with, beside it, like −74%: data-tone="good" or "bad" colours it by whether the change is an improvement; with no data-tone it stays hidden

  ```
  text-xs opacity-0 transition-opacity duration-300
  data-[tone]:opacity-100 data-[tone=good]:text-success
  data-[tone=bad]:text-destructive motion-reduce:transition-none
