This can create either simp le raised-off-the-page effects or a full portal into a 3D world that acts as a window into an independent spatial coordinate system.\n>\n>Existing C SS positioning concepts such as relative and absolute positioning\, inset properties\, anchor positioning\, and box alignment are extended to work a cross all three axes.\n>\n>There are controls that let UAs constrain how f ar content can protrude toward the user\, and capabilities for authors to adapt layouts based on the available spatial depth.\n>\n> to go over this proposal\n\n* [webxr#1396 Confusion around actual and internal visiblity]( https://github.com/immersive-web/webxr/issues/1396) [requested by ibytergj ](https://github.com/immersive-web/webxr/issues/1396#issuecomment-40063792 50)\n> So my use case right now is in VR when the user takes off their hea dset. I want to signal to the system that the avatar should go into an idl e pose so that the avatar is just not collapsing\, whichever way the hands et and controllers happen to be put down. If the headset supports the info rmation like the quest 3 does\, it would be very useful if this informati on was available to us to implement for a better user experience.\n\n### I mmersive Web Community Group Teleconference - 2026-04-21\n\n\n< td> San Francisco (U.S.A. - California)
