Using WML Cards

In a web site, when you click on a hyperlink, it traditionally loads a new page from the web site. As WAP phones can only load pages quite slowly, and the actual connection to the WAP site to request the page typically takes half the download time, wml allows you to load several WAP pages in one go. Each page is stored as a "card" and can be navigated between, just like normal WAP pages, except that as they are already loaded into the phone, they appear instantly to the user. You create a card using the <card id="" title=""> tag, and navigate between the cards using hyperlinks or buttons, but with a # before the name, so to navigate to a card called "cardtwo" your hyperlink will need to ask for "#cardtwo"

An example follows...

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">

<wml>

<card id="MainCard" title="This is the first page"

Hi, this is card one in a multi card wml page
 
<a href="#card2">Go to page two</a>

</card>

<card id="card2" title="This is the second card">

This is the second card
 
<a href="#card3">Go to page three</a>

</card>

<card id="card3" title="This is the third card">

Here is the third page in the multi card wml page
