This Style Guide explains the markup and design requirements for web projects,
along with various standards and best practices.
projects authored in valid XHTML 1.0 Transitional and styled with valid Cascading Style Sheets will be described here.
See the XHTML and CSS sections below for details. Additional sections of this Style Guide, coming soon, will provide
information on writing for the web, naming and filing your documents, and other useful topics and guidelines.
XHTML: Guidelines & Benefits
Library projects must be authored in structural XHTML 1.0 Transitional. Page authors should follow accessibility guidelines in compliance with U.S. Law, and so that our site’s content will be made available to the widest possible number of people, browsers, and Internet devices. In addition, all XHTML must validate.

CSS: Style Sheets & Tips
Library projects must use valid Cascading Style Sheets (CSS) to control typography, color, and other layout elements. Style Sheets must be linked in a way that accommodates the capabilities of new and old browsers.

XML is language independent
By being language independent, XML bypasses the requirement to have a standard binary encoding or storage format. Language independence also fosters immense interoperability amongst heterogeneous systems. It is also good for future compatilbilty. For example, if in the future a product needs to be changed in order to deal with a new computing paradigm or network protocol, by keeping XML flowing through the system, addition of a new layer to deal with this change is feasible.
DOM and SAX are open, language-independent set of interfaces
By defining a set of programming language independent interfaces that allow the accessing and mutation of XML documents, the W3C made it easier for programmers to deal with XML. Not only does XML address the need for a standard information encoding and storage format, it also allows programmers a standard way to use that information. SAX is a very low level API, but it is more than what has been available before it. DOM is a higher level API that even provides a default object model for all XML documents (saving time in creating one from scratch if you are using data is document data).
The situation can become markedly different if we change the vertical
alignment of the inline boxes. Suppose that we change the boldface
text to have a vertical alignment of middle. This
would have the result shown in Figure 8-53.
Figure 8-53. Changing the vertical alignment of the larger text
Here, the middle of the boldfaced text's inline box has lined
up with the middle of the inline boxes of the other text in the line.
Because the inline boxes are all 12px tall, and their middles are all
lined up, this means that the line box for this line is now only 12
