title: "Variable Font Flex"
description: "A word lands while its variable-font weight and width axes flex from hairline-condensed to black-wide with per-character stagger; font-size eases inversely so the letterforms gain mass while the box holds."

import { InstallCommand } from "/snippets/install-command.jsx";
## Install
That writes one file: `compositions/components/variable-font-flex.html`.
## Paste it into your composition
Open `compositions/components/variable-font-flex.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` | `FLEX` | string | The word whose variable-font axes flex. |
| `axis` | `both` | `weight`, `width`, `both` | Which variable-font axes animate: weight, width, or both. |
| `stagger` | `0.06` | number | Seconds between per-character flex starts, clamped 0 to 0.25. |
| `accent` | `green` | `green`, `blue`, `violet` | Word color: green rides --brand, blue rides --accent, violet rides --accent-2. |
| `exit` | `none` | `none`, `fade`, `up` | Optional departure. Default none: the carved word holds until the frame cuts. |
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:
