# Defaults

## Setup

Set defaults in the [settings](/docs/motion/settings/options.md#defaults). There
are two, and both apply on their own once saved; nothing on the page refers to
them.

## Timeline defaults

Timeline defaults are options for every timeline: the
[`tl` timelines](/docs/motion/usage/timelines.md) you declare and the one Motion
creates for each animated element outside them. They use the timeline syntax:

- `defaults:` followed by animation options sets them for every animation in
  the timeline. `defaults:ease-power2.inOut|duration-0.6` gives every
  animation that ease and duration unless it sets its own.
- A plain `option-value` pair, such as `repeat-1`, is an option of the
  timeline itself.

Separate several parts with spaces. Options a `tl` element sets itself win
over the timeline defaults.

## Element defaults

Element defaults are animation parts every animated element starts from,
written like an element's own animation without the class prefix, such as
`from:opacity-0|y-20`. The element's own parts override them, so with those
defaults `animate-from:y-50` still fades in and moves 50 pixels rather than 20.

## ScrollTrigger

Timeline defaults are the place to give every animation a scroll trigger. To
start each animation when its element scrolls into view, set the timeline
defaults to:

```text
scrollTrigger:trigger-[&]|scrub-true
```

`&` is resolved per element, so each element triggers its own animation, and
`scrub-true` ties its progress to the scroll position.
