Active trigger
Learn how to trigger animations on click and hold (active)
Overview
An active trigger executes the animation when element is being activated with click and hold. This is similar to the :active CSS pseudo-class.
Syntax
To activate the active trigger, use the active.
Examples
These examples show the usage of the active trigger in the various timeline types together with the combination with the different triggers.
Discrete timeline
Discrete timeline is the basic timeline that animate the properties when the active trigger is executed on the element.
Sequenced timeline
Sequenced timeline animates the CSS properties in the sequence of steps using the active trigger.
Offset-based timeline
Offset-based timeline combine the CSS-offsets with the sequence of steps to animate the properties, triggered by a active action.
Combination
The active trigger can be combined with any other available triggers.
Parameters
Trigger can be customized with the parameters that are defined within its parentheses ().
Target
The target parameter specifies the external element on the page where the current trigger is applied. This means you can define an animation that starts when a trigger on a different element is activated. A real-world example: clicking the hamburger menu button makes an off-screen sidebar appear.
Options
The id, class and attribute CSS selectors can be used.
| Name | Value | Default | Description |
|---|---|---|---|
target |
class | id | attribute |
null |
CSS selector |
Examples
In these examples, we’ll use a <p id="text"> as the target element where the active trigger is applied. This will then affect elements that reference #text as their target parameter.
For better clarity, you can interpret it as: When the active trigger is activated on the #text target element, the scale(2) CSS property is animated.
