from

from( target:[ Object | Array | String ], vars:Object, position:[ Number | String ] ) : self

Adds a .from() tween to the end of the timeline (or elsewhere using the position parameter) - this is a convenience method that accomplishes exactly the same thing as add( gsap.from(...) ) but with less code.

Parameters

  • target: [ Object | Array | String ]

    Target object (or array of objects) whose properties should be affected. This can also be CSS selector text like "#feature" or "h2.author" (GSAP will pass selector strings to document.querySelectorAll()).

  • vars: Object

    An object defining the starting values for each property that should be tweened as well as any special properties like onComplete, ease, etc.

  • position: [ Number | String ]

    (default = "+=0") — controls the insertion point in the timeline (by default, it's the end of the timeline). See options below, or the Position Parameter article which has interactive timeline visualizations and a video. If you define a label that doesn't exist yet, it will automatically be added to the end of the timeline

Returns : self

self (makes chaining easier)

Details

Adds a gsap.from() tween to the end of the timeline (or elsewhere using the position parameter) - this is a convenience method that accomplishes exactly the same thing as add( gsap.from(...) ) but with less code. For example:

var tl = gsap.timeline();

var tween = gsap.from(element, { duration: 1, x: 100, opacity: 0.5 });
tl.add(tween);

//this line produces the same result as the previous two lines (just shorter)
tl.from(element, { duration: 1, x: 100, opacity: 0.5 });

See the gsap.from() docs for all the details and special properties available for a from() Tween.


You can chain these calls together and use other convenience methods like to(), call(), set(), etc. to build out sequences very quickly:

//create a timeline that calls myFunction() when it completes
var tl = gsap.timeline({ onComplete: myFunction });

//now we'll use chaining, but break each step onto a different line for readability...

//tween element's x from -100
tl.from(element, { duration: 1, x: -100 })

//then tween element's y to 50
.to(element, { duration: 1, y: 50 })

//then set element's opacity to 0.5 immediately
.set(element, { opacity: 0 })

//then call otherFunction()
.call(otherFunction)

//finally tween the rotation of all elements with the class "myClass" to 45 and stagger the start times by 0.25 seconds
.to(".myClass", { duration: 1.5, rotation: 45, stagger: 0.25 });

Positioning animations in a timeline

By default, animations are added to the end of the timeline so that they're sequenced one-after-the-other but you can use the position parameter to control precisely where things are placed. It typically comes after the vars parameter and it uses a flexible syntax with the following options:

  • Absolute time (in seconds) measured from the start of the timeline, as a number like 3

    // insert exactly 3 seconds from the start of the timeline
    tl.from(".class", { x: 100 }, 3);
  • Label, like "someLabel". If the label doesn't exist, it'll be added to the end of the timeline.

    // insert at the "someLabel" label
    tl.from(".class", { x: 100 }, "someLabel");
  • "<" The start of previous animation**. Think of < as a pointer back to the start of the previous animation.

    // insert at the START of the  previous animation
    tl.from(".class", { x: 100 }, "<");
  • ">" - The end of the previous animation**. Think of > as a pointer to the end of the previous animation.

    // insert at the END of the previous animation
    tl.from(".class", { x: 100 }, ">");
  • A complex string where "+=" and "-=" prefixes indicate relative values. When a number follows "<" or ">", it is interpreted as relative so "<2" is the same as "<+=2". Examples:

    • "+=1" - 1 second past the end of the timeline (creates a gap)
    • "-=1" - 1 second before the end of the timeline (overlaps)
    • "myLabel+=2" - 2 seconds past the label "myLabel"
    • "<+=3" - 3 seconds past the start of the previous animation
    • "<3" - same as "<+=3" (see above) ("+=" is implied when following "<" or ">")
    • ">-0.5" - 0.5 seconds before the end of the previous animation. It's like saying "the end of the previous animation plus -0.5"
  • A complex string based on a percentage. When immediately following a "+=" or "-=" prefix, the percentage is based on total duration of the animation being inserted. When immediately following "<" or ">", it's based on the total duration of the previous animation. Note: total duration includes repeats/yoyos. Examples:

    • "-=25%" - overlap with the end of the timeline by 25% of the inserting animation's total duration
    • "+=50%" - beyond the end of the timeline by 50% of the inserting animation's total duration, creating a gap
    • "<25%" - 25% into the previous animation (from its start). Same as ">-75%" which is negative 75% from the end of the previous animation.
    • "<+=25%" - 25% of the inserting animation's total duration past the start of the previous animation. Different than "<25%" whose percentage is based on the previous animation's total duration whereas anything immediately following "+=" or "-=" is based on the inserting animation's total duration.
    • "myLabel+=30%" - 30% of the inserting animation's total duration past the label "myLabel".

*Percentage-based values were added in GSAP 3.7.0
**The "previous animation" refers to the most recently-inserted animation, not necessarily the animation that is closest to the end of the timeline.

Position Parameter Interactive Demo

Be sure to read the Position Parameter article which includes interactive timeline visualizations and a video.

NOTE: By default, immediateRender is true in from() tweens, meaning that they immediately render their starting state regardless of any delay that is specified. You can override this behavior by passing immediateRender: false in the vars parameter so that it will wait to render until the tween actually begins.
