Books

Cascading Style Sheets: Designing for the Web
by Håkon Wium Lie and Bert Bos (Addison-Wesley: 1997)
Though hardly recent (1997), this book has the advantage of having been written by world-class experts. Lie and Bos are W3C members, and Lie is widely considered “the father of CSS.”
Cascading Style Sheets: The Definitive Guide
by Eric Meyer (O'Reilly: 2001)
Eric Meyer is a world expert on CSS, an invited expert to the W3C's CSS Working Group, and currently serves as the Web standards evangelist for Netscape Communications (which is one reason Netscape 6.01 is so much better than Netscape 6.0). His book is both advanced and comprehensive.
Taking Your Talent to the Web
by Jeffrey Zeldman (New Riders: 2001)

You can use the DOM parser to generate the XML for you if you created an object model that is an adapter on top of DOM. Since your object model uses the document object tree, all the information contained in it is actually stored in the tree. The XML parser can take this tree and convert it to XML for you, you can then save this generated XML to a file. So the DOM parser can generate the ApplicationML file for you.

There are advantages and disadvantages to using some of the strategies to import and export XML. The complexity of your application data and available system resources are factors that would determine what strategy should be used.

Client and Server side - Application Servers

By using the contextual selector .sidebar.head, we ensure only those.heads inside a .sidebar willreceive these styles. Since the entire sidebar is already set to useVerdana, the headings will inherit and use it. As for the links, theyneed to be yellow, so we declare:

.sidebar A:link {color: yellow;}.sidebar A:visited {color: yellow;}.sidebar A:active {color: yellow;}
that with the BORDER=0 attribute in the IMG tag. <A HREF="http://www.udel.edu/FREC/spatlab/">
<IMG ALIGN=RIGHT HEIGHT=42 WIDTH=39 HSPACE=5 VSPACE=5 BORDER=0 SRC="tinyearth.gif"></A> The University of Delaware Spatial Analysis Lab is a proud sponsor of this website.  The animated GIF image is also a link.  By default, a linked image has a 2-pixel wide blue border, but I suppressed that with the BORDER=0 attribute in the IMG tag.

While this does rely on inserting an extra element, the advantage is that the SPAN can be placed anywhere in the paragraph and still have the result depicted in Figure 9-21.

However, maybe we'd like to place the change marker next to whatever line was changed. In that case, we need to make only one small alteration to our styles, and we'll get the result shown in Figure 9-22:
