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 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.


with bold as always, while 800 and 900, lacking a heavier face, are assigned to the Bold font face. Finally, 600 is assigned to the next-heavier face, which is, of course, the Bold face.

font-weight is inherited, so if you set a paragraph to be bold, then all of its children will inherit that boldness, as we see in Figure 5-9.

P.one {font-weight: bold;}

close reading of the rules listed earlier will show that the outer edges of a floating element must be within the element's parent. However, negative margins can place the floated element's content such that it effectively overlaps its own outer edge, as detailed in Figure 8-43.

The math in this situation works out something like this: assume the top inner edge of the DIV is at the pixel position 100. The browser, in order to figure out where the top inner edge of the floated

Figure 5-24. Italic and oblique text in detail

Basically, italic text is in some way its own font, with smallchanges made to the structure of each letter to account for thealtered appearance. This is especially true of serif fonts, where inaddition to the fact that the text characters "lean," theserifs may be altered in an italic face. Oblique text, on the otherhand, is simply a slanted version of the normal, upright text. Fontfaces with labels like Italic, Cursive,and
