Easing

Guyn comes with a some default great easing.

The function

To include an Guyn ease use ease($ease-name)

Example :

.mySelector {
	transition: opacity 1s ease(easeInQuad);
}

Will generate :

.mySelector {
	transition: opactity 1s cubic-bezier(0.55, 0.085, 0.68, 0.53);
}

Add custom easing

To overwrite the default easing set and add your own :

// define custom easing
$custom-easing: (
	"ease-header": "1, 1, 1, 1",
	"ease-footer": "1, 0, 0, 1",
);
// add them to the default easing set
$ease: add-custom-easing($custom-easing);

Transitions

Simple transition

A simple mixin for single property transition

@include transition($prop, $timing, $ease, $delay);

variables	type	Description
$prop	String	Property to which transition should be applied
$timing	`Number	String`
$ease	String	Timing function
$delay	`Number	String`

::: tip @henris/utils/index has to be imported before using the mixin. :::

Example :

// with duration number
.element {
	@include transition("opacity", 500, linear, 0);
}
// with string duration
.element {
	@include transition("opacity", 0.5s, linear, 0s);
}

Will generate:

// with duration number
.element {
	transition: opacity 500ms 0s cubic-bezier(0.25, 0.25, 0.75, 0.75);
}
// with string duration
.element {
	transition: opacity 500ms 0s cubic-bezier(0.25, 0.25, 0.75, 0.75);
}

Multiple transition proprieties

Guyn comes with a mixin to easily define a bunch of transitions on the same element. The transition-group mixin will also generate the will-change property.

// list definition
$transitions: (
	($prop, $timing, $delay, $ease),
	($prop, $timing, $delay, $ease),
	...
);
@include transition-group($transitions);

Each row of the transition list as to be defined by these 4 arguments in the order listed.

variables	type	Description
$prop	String	Property to which transition should be applied
$timing	`Number	String`
$delay	`Number	String`
$ease	String	Timing function

Example :

$transitions: (
	("opacity", 500, 0, linear),
	("transform", 700, 0, ease),
	("color", 500, 0, easeInQuad)
);
.element {
	@include transition-group($transitions);
}

Will generate:

.element {
	transition: opacity 500ms 0ms cubic-bezier(0.25, 0.25, 0.75, 0.75), transform
			700ms 0ms cubic-bezier(0.25, 0.1, 0.25, 1),
		color 500ms 0ms cubic-bezier(0.55, 0.085, 0.68, 0.53);
	will-change: opacity, transform, color;
}
