Create an animation with start and end properties:

fadeOut : Animation
fadeOut =
    Animation.fromTo
        { duration = 1000
        , options = []
        }
        [ P.opacity 1 ]
        [ P.opacity 0 ]

Create an animation with multiple steps:

backAndForth : Animation
backAndForth =
    Animation.steps
        { startAt = [ P.x 0 ]
        , options = []
        }
        [ Animation.step 1000 [ P.x 100 ]
        , Animation.step 1000 [ P.x 0 ]
        ]

Animate to a list of properties for a given number of milliseconds:

Animation.step 1000 [ P.opacity 1 ]

Set a list of properties immediately in an animation (This is equivalent to step 1):

Animation.set [ P.opacity 0 ]

Wait for a given number of milliseconds before animating the next properties:

Animation.wait 1000

Wait for another animation to complete before animating the next properties:

This animation will wait for 1500 milliseconds before animating to the next step

finishAfterFadeOut : Animation
finishAfterFadeOut =
    Animation.steps
        { startAt = [ P.x 0 ]
        , options = []
        }
        [ Animation.step 500 [ P.x 20 ]
        , Animation.waitTillComplete fadeOut
        , Animation.step 500 [ P.x 60 ]
        ]


fadeOut : Animation
fadeOut =
    Animation.fromTo
        { duration = 2000
        , options = []
        }
        [ P.opacity 1 ]
        [ P.opacity 2 ]

Repeat an animation forever

Play an animation a given number of times

Delay the start of an animation (repeats like loop or count are not affected by this)

Get the duration of an animation
