Introduction

Uniform Resource Locators (URLs) are being used to name resources in WML. There are two different
types of URLs: absolute and relative URLs. A WML fragment anchor is specified by suffixing the URL
for a deck with a # symbol and the destination element’s id attribute is added as follows:

deck-url#card-id

Example: If we want to refer to the “menu” card in mydeck, we have to use an absolute
URL such as http://www.peterindia.net/mydeck.wml#menu.
In this unit we will discuss about the card navigation.
