• proposals#91 Spatial CSS Interest requested by AdaRoseCannon

Hi, we have published our proposal for Spatial CSS here:

• Explainer: https://webkit.github.io/explainers/css-spatial/explainer.html.
• Spec: https://webkit.github.io/explainers/css-spatial/Overview.html

The goal of this work is to let web authors build in-page spatial experiences using familiar CSS patterns.

This introduces three-dimensional layout to CSS, allowing elements to be positioned toward and away from the user. This can create either simple raised-off-the-page effects or a full portal into a 3D world that acts as a window into an independent spatial coordinate system.

Existing CSS positioning concepts such as relative and absolute positioning, inset properties, anchor positioning, and box alignment are extended to work across all three axes.

There are controls that let UAs constrain how far content can protrude toward the user, and capabilities for authors to adapt layouts based on the available spatial depth.

• webxr#1396 Confusion around actual and internal visiblity requested by ibytergj

So my use case right now is in VR when the user takes off their headset. I want to signal to the system that the avatar should go into an idle pose so that the avatar is just not collapsing, whichever way the handset and controllers happen to be put down. If the headset supports the information like the quest 3 does, it would be very useful if this information was available to us to implement for a better user experience.
