css: Enable `jump-start`, `jump-both`, `jump-end`, `jump-none` step-position by yezhizhen · Pull Request #43061 · servo/servo

yezhizhen · 2026-03-06T14:17:21Z

Bumps stylo to servo/stylo#323
As tested with examples, all step-position keywords now work: https://drafts.csswg.org/css-easing-2/#typedef-step-position

Testing: New passing WPT. Several in moveBefore goes from TIMEOUT to FAIL, as the API is not enabled in Servo. Added 4 new tests to test the proper rendering.
Fixes: #43060

⚠️ Try run (#22767317286) failed!

TimvdLippe · 2026-03-06T19:09:29Z

FYI @lukewarlow about moveBefore tests

xiaochengh

Just let me try to understand the situation: these keywords are already implemented in Servo, and the only thing we need to do is to enable parsing?

yezhizhen · 2026-03-07T05:25:11Z

the only thing we need to do is to enable parsing

@xiaochengh Indeed. They were tested with examples in #43060.
The moment you discover that only some keyword are supported make you wonder how is that possible,
since these are all just animation with discrete easing functions.
We even support continuous cubic-beizer timing function, which is more complex.

before-fix.mp4

post-fix.mp4

yezhizhen · 2026-03-07T05:33:18Z

these keywords are already implemented in Servo

@xiaochengh The animation progress calculation is done In Stylo instead of Servo: relevant stylo code

All servo did is retrieving the computed animation_declarations:

servo/components/script/layout_dom/element.rs

Lines 280 to 282 in 42d228d

 context.animations.get_animation_declarations( 

 &AnimationSetKey::new_for_non_pseudo(node.opaque()), 

     context.current_time_for_animations,

yezhizhen · 2026-03-07T10:47:08Z

@Loirooriol Do you think we should add 4 ref tests? My idea is to use comibination of negative delay (necessary to distinguish between jump-none and jump-end) to test certain frame.

Right now these tests are written with Web Animations API, which we don't support... None of the passing tests involve actual animation rendering.

servo/tests/wpt/tests/css/css-easing/step-timing-functions-output.html

Lines 106 to 118 in 9394cdf

 test(function(t) { 

 var target = createDiv(t); 

 target.style.position = 'absolute'; 

 var anim = target.animate([ { left: '0px', easing: 'step-end' }, 

 { left: '100px' } ], 

 { duration: 1000, 

 fill: 'forwards', 

 easing: 'cubic-bezier(0, 1.5, 1, 1.5)' }); 

 // The bezier function produces values greater than 1 (but always less than 2) 

 // in (0.23368794, 1) 

 anim.currentTime = 0; 

 assert_equals(getComputedStyle(target).left, '0px');

Loirooriol · 2026-03-07T11:03:12Z

Sounds good. Indeed using paused animations with a negative delay, you can check the outcome at the desired %

yezhizhen · 2026-03-07T11:23:29Z

Sounds good. Indeed using paused animations with a negative delay, you can check the outcome at the desired %

Speaking of which, we have another bug: #43080, that blocks us from testing multiple % in one test.. Guess we just test one single critical then..
