Certain Primer Brand components include animation presets. These components are:
Box
, Button
, ComparisonTable
, FAQ
, Image
, Heading
, Label
, Pillar
, SectionIntro
, Stack
, Statistic
, Testimonial
, Text
, Timeline
, Animate
, River
, RiverBreakout
You can use the animate
prop available on these components to apply one of the available animation presets directly to the component.
<Image animate="fade-in" />
You can alternatively compose animations into your React application using the Animate
wrapper component. This can be useful in situations where you need to animate native HTML elements, or components that don't support the animate
prop.
import {Animate} from '@primer/react-brand'
<AnimationProvider><Animate animate="fade-in"><Text>This text will fade-in</Text></Animate></AnimationProvider>
An AnimationProvider
is first required to enable animations on the page. This component should wrap specific parts of your application code, or the entire app.
The AnimationProvider
assumes responsibility for triggering animations and automatically applying effects such as staggering.
By default, the AnimationProvider
will stagger animations in order of DOM appearance. This behavior can be turned off by setting autoStaggerChildren
to false
.
The increment delta can also be increased or decreased using staggerDelayIncrement
, which is set to 100ms by default.
import {AnimationProvider} from '@primer/react-brand'
Supported animations types include:
fade-in
, fade-out
, slide-in-up
, slide-in-down
, slide-in-left
, slide-in-right
, scale-in-up
, scale-in-down
, scale-in
, fill-in-top
, scale-in-right
, scale-in-left
, fill-in-right
To use a specific animation variant, simply pass the animate
prop with the desired variant. This value can either be a string
or and Object
. The latter provides more granular control over the animation delay, durations and easing.
Use the example below to try each animation variant.
Animations should be used sparingly. The examples below demonstrate some valid use-cases.
Apply animation to River.Content
instead of the entire element.
AnimationProvider
automatically applies a delay increment to all children
that have animation
presets defined. Extend the duration of each delay using staggerDelayIncrement
.
Alternatively, use delay
to stagger animations on adjacent elements if this feature is toggled off.
See Storybook for more examples of animation.
Name | Type | Default | Required | Description |
---|---|---|---|---|
children | ReactNode | true | The children to render within the AnimationProvider | |
disableAnimations | boolean | false | Prevents animations from running inside the provider | |
animationTrigger | 'click' 'on-visible' | 'on-visible' | false | Controls the trigger method for the animation. One of click or on-visible . |
visibilityOptions | 'bottom-of-screen' 'middle-of-screen' 'about-to-leave' 'number' | 'bottom-of-screen' | false | Controls the intersection observer options for the animation. |
runOnce | boolean | false | false | Will persist the animation end-state after the animation has completed. |
autoStaggerChildren | boolean | true | Will stagger the animations of the children using an incrementing delay | |
staggerDelayIncrement | number | 100 | Stagger delay increment. Should be used alongside autoStaggerChildren . |
