Spec
https://drafts.csswg.org/css-round-display-1/#shape-media-feature

Summary
The shape media query feature describes the general shape of the targeted display area of the output device.

 

This media query feature has been updated in CSS Round Display spec as follows:

- The name of 'device-radius' is changed to 'shape' .

- The functionality of the media feature('shape')  is the same as the old name('device-radius').

- The value set is changed from numbers([<length>|<percentage>]) to strings(rect|round).

 

The original intent to implement:

CSS WG discussion on the spec change:

https://lists.w3.org/Archives/Public/www-style/2016May/0233.html

Motivation
There are many devices with the round display on the market such as smart watches and thermostat so web developers needs to know the display shape to apply specific CSS styles according to the display shape.

 

Interoperability risk
Firefox: No public signals
Edge: No public signals
Safari: No public signals
Web developers:  Positive

Compatibility risk
None.

Ongoing technical constraints
None.

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

Yes, it will be supported on all platforms, but the value can be “round” or “rect” on Android and Linux. If others platforms support the round display in the future, we can add the support.

Hello,

I found some dead SetDisplayShape code in LocalFrameView today and it led me back to here. Is this still being implemented?

Thanks,

Dana

Sounds like this isn't happening.. What is the procedure for removing code that is no longer under development? Is there a process of notification or a timeline specified that I should wait for?

Thanks!

Dana

as this isn't yet launched, there is no process to follow

Hi,

I have a local patch for Android backend that uses SetDisplayShape code, but I’m not sure if Android Wear supports WebView or a Web Browser.

Thanks,

Joone

Android Wear does not include WebView (it was disabled for space/memory reasons), and there's no supported web browser either (though I think there are some third party apps that embed somebody's web rendering engine anyway - no idea if they're based on chromium or not)
