A.3. Online Communities

One can read only so much before it comes time to join a discussion and ask some questions. There are two major venues for discussions about CSS, but each is concerned with a specific type of discussion -- so make sure you go to the right place.

A.3.1. comp.infosystems.www.authoring.stylesheets

This Usenet group, often abbreviated as ciwas (pronounced "see-wass"), is the gathering place for CSS authors. A number of experts in the field check this newsgroup regularly, this author among them, and all are there for one primary reason: to help new CSS authors over the hurdles that learning any new language will generate. The secondary reason is for the spirited debates that occasionally erupt over some aspect of CSS, or a browser's implementation thereof. Rather unusually for a newsgroup, the signal-to-noise ratio stayed fairly high for the last few years of the 1990s, and will with any luck continue in that vein.

A.3.2. www-style@w3.org

Anyone who wishes to be involved in discussing the future course of CSS, and to clearing up ambiguities in the specifications, should subscribe to this list. The members of the list are all, in one are assigned to the Regular face because there isn't a lighterface available. 400 goes to Regular as expected,but what about 500 ? It is assigned to the Regular(or normal) face because there isn't aMedium face available; thus, it is assigned the same as400. As for the rest, 700 goeswith bold as always, while 800and 900, lacking a heavier face, are assigned tothe Bold font face. Finally, 600 is assigned tothe next-heavier face, which is, of course, the Bold face. fashion or another, interested in making CSS better than it is already. Please note: www-style is not the place to ask for assistance with writing CSS. For help with CSS authoring problems, visit ciwas instead. Questions beginning with "How do I ... ?" are frowned upon by the regulars of www-style and are usually redirected to a more appropriate forum such as ciwas. On the other hand, questions that begin "Why can't I ... ?" or "Wouldn't it be cool if ... ?" are generally welcome, so long as they relate to some ability that appears to be missing from CSS.

Messages to www-style are only accepted if the sender is already subscribed to the list. In order to subscribe, send email to with the word subscribe in the subject of the message; to unsubscribe, send email to with the word unsubscribe in the subject of the message.

In an attempt to address this situation,displays such as monitors usually have a default gammavalue set; this is a factor that modifies colorsto account for display conditions. The gamma is typically set via theoperating system, although more expensive monitors may have their owngamma settings. The problem is that different systems have different
