Thanks Daniel, the 
CL<https://chromium-review.googlesource.com/c/chromium/src/+/3690356> has 
landed !
Also, I had added a base::Feature 
flag<https://chromium-review.googlesource.com/c/chromium/src/+/3652981> a 
couple of weeks ago. I’m assuming that should make it controllable remotely. If 
not, please let me know.

PS: Thank you all for your reviews on this feature. We appreciate it… 😊
I will keep an eye out for any issues that pop up in the coming days.

Thanks,
Rahul

You have the approval needed for shipping on stable, i.e. land that patch. It 
will get some testing by going through Canary and Beta releases, but if you 
feel some uncertainty you can also add the plumbing that would let it be turned 
off remotely (flags, finch). You will need some assistance by Google employees 
for that though.

[blink-dev] Intent To Ship: Prevent fixed elements from moving during elastic overscroll.

2022-05-24 Thread &#x27;Rahul Arakeri&#x27; via blink-dev 
Contact emails: arak...@microsoft.com



CSSWG discussion: [css-overscroll] Whether to move position:fixed elements 
during overscrolling * Issue #6299 * w3c/csswg-drafts 
(github.com)



Summary: Currently, position:fixed elements move when the scroller is 
overscrolled. With this change, we intend to prevent fixed elements from moving 
during an elastic overscroll.



Blink component: 
Blink>Scroll



Chromestatus: Prevent overscroll for fixed elements. - Chrome Platform Status 
(chromestatus.com)



Risks:

  *   Interoperability: Firefox/Safari still moves fixed elements on 
overscroll. Interacting with websites will feel different (going forward) on 
platforms that support overscroll. This may lead to some web devs amending 
pages to preserve their original UX. We are currently running experiments in 
Microsoft Edge to determine user impact and would also discuss the possibility 
of doing origin trials in Chromium with Google engineers.



Debuggability: N/A


Is this feature fully tested by web-platform-tests?

Yes. We did a dry 
run with the 
feature turned on and noticed test failures. They will need to be addressed 
before the feature can be turned on.


Flag name: FixedElementsDontOverscroll

  *   Usage: chrome.exe --enable-features=ElasticOverscroll 
--enable-blink-features=FixedElementsDontOverscroll



Estimated milestone:

105



Tracking bugs:

  *   Chromium:
 *   585766 - Overscroll shouldn't affect fixed elements - 
chromium
  *   Firefox:
 *   https://github.com/mozilla/wg-decisions/issues/757
 *   https://bugzilla.mozilla.org/show_bug.cgi?id=1760368

Adding onto Rahul's answer here a little - overlay scrollbars (or scrollbars

default on OSX). It won't/shouldn't be a web compat concern as most websites 
handle this already.

An interesting side effect of this will likely be that we'll see more sites 
(who are built after this change goes in) assume that scrollbars are always 
zero width (as this is now the default on all platforms except linux?) and as a 
result more content going forward being broken for those users who opt-out.

non-overlay) to fit the Windows 11 Fluent design language. As a part of this 
effort, we are proposing to update the visual appearance along with some 
changes to how users interact with overlay scrollbars.



Motivation

As the rest of Windows has been embracing WinUI and native Fluent controls, 
certain non-XAML apps like Chromium-based browsers still use the traditional 
(Win32 looking) scrollbars. As such, we believe that the visual appearance of 
scrollbars could use an update in the interest of maintaining homogeneity with 
the rest of Windows.

In a nutshell, we’re proposing that the default scrollbars should act more like 
overlay scrollbars, be thinner, have insets and rounded edges. Users will still 
have an option to select non overlay scrollbars via the "Always show 
scrollbars" OS setting. Non overlay scrollbars will also be restyled to match 
Windows theme. For details on scrollbar styling and state transitions, please 
see the visual spec linked above.

Also, please note that since some HTML controls (like  and ) 
depend on the ScrollbarThemes(s) that are being refreshed, they too will also 
get the new scrollbars.



Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, 
Chrome OS, Android, and Android WebView)?

No, this is aimed at Windows for now. However, it can be made available on 
Linux too.



Ongoing technical constraints

None.

Summary

This proposal is to modernize the Chromium scrollbars (both overlay and 
non-overlay) to fit the Windows 11 Fluent design language. As a part of this 
effort, we are proposing to update the visual appearance along with some 
changes to how users interact with overlay scrollbars.



Motivation

As the rest of Windows has been embracing WinUI and native Fluent controls, 
certain non-XAML apps like Chromium-based browsers still use the traditional 
(Win32 looking) scrollbars. As such, we believe that the visual appearance of

the rest of Windows.

In a nutshell, we’re proposing that the default scrollbars should act more like 
overlay scrollbars, be thinner, have insets and rounded edges. Users will still 
have an option to select non overlay scrollbars via the "Always show 
scrollbars" OS setting. Non overlay scrollbars will also be restyled to match
