# Headline Slam
A heavyweight headline scales down into frame, lands with a deterministic three-frame shake, holds with subtle drift, and whips upward on exit.
**Headline Slam**
```html headline-slam.html
Headline Slam
```
Copy npx hyperframes add headline-slam to the clipboard
That writes one file: `compositions/components/headline-slam.html`.
## Paste it into your composition
Open `compositions/components/headline-slam.html` and copy what is inside into your own composition.
A component has no size or duration of its own. It takes both from the composition
you paste it into.
## Variables
Every one of these has a default, so the piece works untouched. Set the ones you
want to change on the element:
| Variable | Default | Accepts | What it does |
| - | - | - | - |
| `text` | `Ship it today` | string | Text displayed as the headline. |
| `accent_word_index` | `1` | number | Zero-based word index to color. Out of range leaves the headline unaccented. |
| `accent` | `green` | `green`, `blue`, `violet` | Color applied to the selected word. |
| `shadow` | `true` | boolean | Drop shadow cast under the headline. On by default; set false for a flat matte look. |
Set them with `data-variable-values` on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:
```html wrap
```
{/* hf:generated-footer */}
Tagged `motion-primitive` `typography` `headline` `slam` `impact` `exit`.
