Since it's not even available in Canary yet the label M-46 is not accurate, isn't it?

Comment 6 by, Sep 23 2015

(unless that's just for Android or sth)

Labels: -M-46 OS-Android
Right, M46 was our original goal.  Removing the milestone for now.

Any ETA on this feature?
I cannot provide and ETA but in case it helps we are ramping up our efforts here.

I have been hoping that Chrome would implement this for a long time. Are you guys still working on it? Chrome is the last browser to implement this before we can finally drop all our nasty scroll snapping polyfill scripts.
Status: Started (was: Assigned)
It is in our backlog. We like the new spec and understand it can help get rid of those polyfills.

In future if you just want to indicate your interest in any feature or bug on, please star the bug which is more appropriate than leaving a comment.
Thanks i have it starred, but there was no activity (seemingly) for a long
time that's why I asked. Thanks for the status update and great that you
are still working on it. I was getting a bit worried to be honest :)

Can be assigned another owner developer?
Because. Owner: Last visit 22 days ago

majidp@ is currently on paternity leave, but sunyunjia@ is actively working on code (presumably under  issue 311234 ) and Majid is still driving the overall effort.

Need add link `launch bug` to page Status in Chromium
Could it be possible to raise the priority of this issue since it has been open for so long? 

Scrolling is a hugely important feature of any app and no app can use CSS Scroll Snap points without ugly polyfills because Chromium is the dominant browser (especially on mobile where the polyfill performance cost is highest) and has still not implemented it. I think this issue is being worked on for over almost 2 years now.

Labels: migrated-launch-owp Type-Task
This issue has been automatically relabelled type=task because type=launch-owp issues are now officially deprecated. The deprecation is because they were creating confusion about how to get launch approvals, which should be instead done via type=launch issues.

We recommend this issue be used for implementation tracking (for public visibility), but if you already have an issue for that, you may mark this as duplicate.

For more details see here:

For any questions, please contact owencm, sshruthi, larforge
It would be great to get an update on this issue. Is there an ETA?

Support in other browsers is now:
Internet Explorer: Shipped
Firefox: Shipped
Safari: Shipped

Chrome is now the only browser not supporting this amazing feature for performant web app usability.
They're doing it from the ground up on top of low-level primitives to make sure the implementation is maintainable and performant, instead of just bolting it on. 

Is still blocked on? 
What's the status now that CSS smooth scrolling has been activated in Chrome? From my understanding, CSS smooth scrolling as well as CSS Scroll Snap Points both were blocked by the very same low-level primitive creation task.
No lower level primitive is blocking our progress for scroll snap. We are actively working on it and making progress. See my other comment here [1].

The following revision refers to this bug:

commit 15ccae56cd1e6de0026e5dc0507192edcefe1932
Author: Sandra Sun <>
Date: Wed Jan 03 17:26:52 2018

Turning CSSScrollSnapPoints experimental.

As we have implemented Snap at GestureScrollEnd on main thread,, we'd
like to turn the flag to experimental so it would be easier to test the
feature on Canary.

MACOS - Chrome Canary 66.0.3339.0
In chrome://flags/ not found flag CSS Scroll Snap
It's one of "Experimental Web Platform features", could you try to turn on that flag?
