CSS Style Guide

 

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.

Another example is web enabling legacy systems. It is very feasible to create a Java web ennoblement application server that simply uses the services provided by the underlying legacy system. Instead of rewriting the legacy system, if the system can be made to communicate results and parameters through XML, the new and old system can work together without throwing away a company's investment in the legacy system.

XML is an open standard

By making the W3C the keeper of the XML standard, it ensures that no one vendor should be able to cause interoperability problems to occur between systems that use the open standard. This should be reassuring to most companies making an investment in this technology, by being vendor neutral, this solution proposes to keep even small companies out of reach of big companies choosing to change the standards on them. For example, if a big company chooses to change the platform at its whim, then most other companies relying on that platform suffer. By keeping all data in XML and using XML in communications protocols, companies can maximize the lifetime of their investment in their products and solutions.

XML is language independent

In order to get from this simplified state to something morefamiliar, all we have to do is determine how wide the element shouldbe, and then break up the line so that the resulting pieces will fitinto the width of the element. Thus we arrive at the state shown inFigure 8-46.

Basically, nothing's changed. All we did was take the singleline and break it into pieces, and then stack those pieces on top ofeach other. Piece of cake.
