Purpose of "UNKNOWN" selector in some style sheets

I have noticed the presence of declarations like this:

UNKNOWN {
height: 30px
}

in the style sheets used by some highly regarded CSS folks. This
declaration usually (but not always) follows a declaration ending with
"voice-family: inherit."

I assume this is some CSS hack, but I can't find anything on the web
discussing this declaration.

Thanks

My guess is that you're looking at a CSS file you saved to your hard
drive, and that furthmore you saved it using IE/Win, probably but not
necessarily IE5.5 or earlier. When you save a style sheet via IE/Win,
it doesn't save the actual file on the server you've visited, but
instead saves a dump of the style sheet as it's represented within IE's
DOM. If you want to see what people are really doing in their style
sheets, go to the actual CSS file on the server and save that.
And it sounds like you're seeing the results of the Box Model Hack
(http://tantek.com/CSS/Examples/boxmodelhack.html) confusing the browser.

Hi, Just how do you track down the location of an exception when all you get is a message saying "NullReferenceException occured in Unknown Module" ?

On 7.4.6, is there any problem with defining one column of a view to be a string literal? For example ... $ psql -c "create view fooview as select 'bar' as footype" WARNING: column "footype" has type "unknown" DETAIL: Proceeding with relation creation anyway. CREATE VIEW Or is this warning just noise in this case?

IE7 returns "unknown" instead of "undefined" when querying the type of an unknown property of an object, for example document.write(typeof window.missingproperty); Has "unknown" been defined as a valid return value for the typeof operator in a later version of ECMAScript or is this a JScript "feature"? -- Klaus Johannes Rusch
