3.5. <wml>
Element
<wml>
is the root element of WML. All other elements should be enclosed
within the <wml></wml> tags.
3.6. <card>
Element
The
<card> element specifies the content of a card. There are two
cards in our Hello World WML example. As you can see in the earlier
screenshots, only one card is displayed at a time. We will discuss
how to navigate from one card to another when we talk about anchor
links later in this tutorial.
In
our Hello World WML example, two attributes, id and title,
have been specified to the <card> tag. We use the id
attribute to define a unique ID for a card. Card IDs are needed for
navigation between cards. However, the id attribute has no use
in the Hello World WML example and it is OK to remove it.
The
title attribute is used to set the title of a card. Typically,
a title is displayed at the top of a wireless device's screen. Most
WAP browsers display the title of a card, although a few very old
ones do not. If the title is too long, WAP browsers will truncate the
title to match the size of the title bar.
Unlike
HTML 4.01 Transitional, text cannot be enclosed directly in the
<card></card> tag pair. For example, the following markup
code is incorrect in WML:
<card
id="card1" title="WML Tutorial"> Hello
world. Welcome to our WML tutorial. </card>
To
correct the above WML markup code, enclose the text in <p></p>
tags. The following markup code is the correct version of the
previous one:
<card
id="card1" title="WML Tutorial"> <p>Hello
world. Welcome to our WML tutorial.</p> </card>
