This ca n 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 sys tem.\n\nExisting CSS positioning concepts such as relative and absolute po sitioning\, inset properties\, anchor positioning\, and box alignment are extended to work across all three axes.\n\nThere 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.\n\nto go over this proposal\n\nImmersive Web Community Group Teleconference - 20 26-04-07\nSan Francisco (U.S.A. - California) Tuesday\, April 7 at 11:00 A M PDT\nBoston (U.S.A. - Massachusetts) Tuesday\, April 7 at 2:00 PM EDT\nL ondon (United Kingdom - England) Tuesday\, April 7 at 7:00 PM GMT+1\nParis (France) Tuesday\, April 7 at 8:00 PM GMT+2\nTokyo (Japan) Wednesday\, Ap ril 8 at 3:00 AM GMT+9\nCorresponding UTC (GMT) Tuesday\, April 7 at 6:00 PM UTC\nLogistics\nChair: Ada Rose Cannon\n\nScribe:\n\nIRC: irc.w3.org:66 67 #immersive-web Instructions\n\nCall Details can be found in the Immersi ve Web Event Calendars: WG/CG\n\nYou subscribe to these calendars with you r calendar application of choice for more convenient access to the call de tails.
