# Notification Pileup
Mobile notification cards arrive faster and faster, each new alert pushing the existing stack downward into a dense, anxious tower.
**Notification Pileup**
```html notification-pileup.html
Notification Pileup
```
Copy npx hyperframes add notification-pileup to the clipboard
That writes one file: `compositions/components/notification-pileup.html`.
## Paste it into your composition
Open `compositions/components/notification-pileup.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 |
| - | - | - | - |
| `count` | `7` | 4 to 10, step 1 | Number of notification cards in the final pile. |
| `speed` | `1` | 0.5 to 2, step 0.1 | Pacing multiplier for the accelerating notification arrivals. |
| `showBadges` | `yes` | `yes`, `no` | Show or hide unread count badges on the notification cards. |
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 `notification` `mobile` `ui-props` `overload` `pileup` `loop` `agitate`.
