But .... I wonder if this spec is implemented properly in enough common browsers. Does anybody know?
I could do some really cool shit with this, but I don't want to waste my time if it's going to only 80% work in 95% of browsers. Or, I could just go all 1995 and put up "This site best view with Netscape 12.0!" all over my sites.
Update: *sigh*... not perfectly with Mozilla.
