XHTML: What is XML?
XML (Extensible Markup Language) is a “super” markup language from which programmers can develop other, custom markup languages and specialized applications. XHTML (Extensible Hypertext Markup Language) is one such markup language.
Programmers already use XML for database and catalog work, and XML also acts as the foundation for standard web protocols including Scalable Vector Graphics (SVG), Synchronized Multimedia Integration Language (SMIL), Wireless Markup Language (WML), and Platform for Privacy Preferences (P3P).
For information about these web protocols, visit W3C.
Figure 4-34. Bottom alignment
As you can see from Figure 4-34, the second line ofthe paragraph contains two images, and their bottom edges are alignedwith each other. (The first image has been set to a middle alignmentusing the HTML attribute align. We'll lookinto ways of achieving a similar effect with CSS a little later inthis chapter.)
