center a FIXED BOX

This BOX has a fixed width.
It is centered and adjusts to the browser window.
The height adjusts to the content.

body {

blank space between the content box and the borders. Altogether, itisn't a very pretty picture.

6.1.3. Special Effects

Let's return to the happier realmof how things should work. Thanks to color andbackground-color, you can create some nice

P {margin: -10%;}

Figure 7-20 illustrates the consequences of such a rule, where the amount by which paragraphs overlap each other and spill beyond the browser window is entirely dependent on the width of the window itself -- and the wider the window, the worse the situation becomes.

Using negative Inheriting color

By this time, you may have guessed that color is inherited, and you're right. This makes good sense, since if you declare P {color: maroon;}, you probably expect that any text within that paragraph will also be maroon, even if it's emphasized or boldfaced or whatever. Of course, if you want such elements to be different colors, XML documents are also naturally committed to a database (relational or object) or any other kind of XML document store. There are commercial products available which allow you to save XML documents to an XML storage layer (which is not a database per se), like Datachannel's XStore and ODI's eXcelon. These XML store solutions are quite expensive ($10,000 to $20,000 range).

XML documents are also quite naturally retrieved from a persistence layer (databases, file systems, XML stores). This lends XML to be used in real world applications where the information being used by different parts of a system is the most important thing.

XML is platform independent, textual information

Information in an XML document is stored in plain-text. This might seem like a restriction if were thinking of embedding binary information in an XML document. There are several advantages to keeping things plain text. First, it is easy to write parsers and all other XML enabling technology on different platforms. Second, it makes everything very interoperable by staying with the lowest common denominator approach. This is the whole reason the web is so successful despite all its flaws. By accepting and sending information in plain text format, programs running on disparate platforms can communicate with each other. This also makes it easy to integrate new programs on top of older ones (without rewriting the old programs), by simply making the interface between the new and old program use XML.

For example, if you have an address book document stored in an XML file, created on a Mac, that you would like to share with someone who has a PC, you can simply email them the plain text address book XML document. This cant be done with binary encoded information which is totally platform (and program) dependent.
