There should be a space between the star and html:

Indeed.
This will not make it valid.
Nope. * html {} is perfectly valid (CSS1, 2, 3, 4, and beyond).
In a decent browser, it won't select anything and nothing though...
That hack relies on the fact that the simple little mind of IE 6& 7
‘thinks’ there is an element that wraps around the root element
(html). Of course there is none.

This is not correct. For IE6 and earlier, there is an element outside
<html>. I received this message offlist (not stating the list) in 2008.

This means that IE6- sees this.
<root-container>
<html> ... </html>
</root-container>
This bug was partly corrected in IE7 but the universal selector '*' was
now selecting the <!doctype> as if it was an element. This is why a
sibling selecting was needed in the IE7 only hack.
*+html { /* IE7 style */ }
<!doctype> + <html>
For anyone following this thread, the below article gives some history
of IE hacks (with links). The article is worded to suit the times of IE8
beta release.
